SD系列保护设备产品介绍说明书

The SD Series is a range of surge protection devices combining unparalleled packing densities, application versatility, proven reliable hybrid circuitry, simple installation and optional ‘loop disconnect’facilities – features which make the series the ultimate surge protection solution for process equipment, systems I/O and communications networks.The exceptionally high packing densities are the consequence of an ultra slim ‘footprint’ for individual modules which can thus ‘double-up’ as feedback terminals. Each module provides full hybrid surge protection for 2 and 3 wire loop protection.Modules with a comprehensive range of voltage ratings cover all process related signals such as RTDs, THCs, 4 to 20mA loops, telemetry outstations, shut-down systems and fire and gas detectors. Optional ‘loop disconnect’,is a feature which allows commissioning and maintenance to be carried out without removal of the surge protection device.This facility is provided by the SD07, SD16,SD32 and SD55 units. In addition, a thirdconnection on the field and safe side ofthe protector is provided in order toterminate screens safely.For three wire applications the speciallydesigned SD RTD(ResistanceTemperature Detector) and the SD32T3,(for separately powered 4-20mA loops)provide full 3-wire protection in a singlecompact unit. The recommended choicefor the protection of 3-wire pressuretransducers on low power circuits is theSD07R3.For higher bandwidth applications,theSDR series has been developed to meetthe demands of today’s highest speedcommunication systems.120V and 240V AC versionsare available for I/O andpower supplies up tothree Amps of loadcurrent.Telephone networks can be protected bythe SDPSTN.One simple manual operation clampsmodules securely onto DIN rail, whichautomatically provides the essential high-integrity earth connection.‘Top-hat’ (T-section) DIN rail is generallysuitable for mounting SD modulesalthough for adverse environments, aspecially-plated version is available fromMTL Surge Technologies. Acomprehensive range of mounting andearthing accessories can also besupplied, see page 7 for furtherdetails.Ultra-slim user-friendly devices for protecting electronic equipment and systems against surges on signal and I/O cablingSD SeriesO Range of ATEX Certified intrinsically safe surge protectorsO Ultra-slim space-saving design; easy installationO Multistage hybrid protection circuitry – 10kA maximum surge currentO Range of voltage ratings -- to suit all process I/O applicationsO High bandwidth, low resistance, RTD, PSTN and 3-wire transmitter versions availableGuide to applications and selectionAnalogue inputs(high-level)2-wire transmitters, 4-20mA, conventional and smartThe SPDs recommended for use with ‘conventional’and ‘smart’ 4-20mA transmitters(fed by a well-regulated supply) are the SD32 and SD55, the choice depending upon the maximum working voltage of the system (32V and 55V respectively). The diagram illustrates a prime example of an application for which the fuse/disconnect facility is particularly useful, however, both models are available in ‘X’versions without the optional fuse/disconnect feature.Analogue inputs(low-level)RTDsThese applications are best served using the SD RTD. F or optimum accuracy, the energising current should be chosen to ensure the voltage across the RTD does not exceed 1V over the full measurement range. When using a PT100 device, we recommend an energising current of 1mA.ac sensors, photocells, THCs, mV sources and turbine flowmetersThe SD07 or SD16 (depending upon the operational voltage) are the favoured choices for this application. SD07X and SD16X are also suitable.4561232xSD16X, SD32XPIVOVSD16 SD32 SD55SD16X SD32X SD55X (no fuse)456123SDVLogic signalOVSD07 SD16 SD32 SD55SD07X SD16X SD32X SD55X (no fuse)456123LED AlarmSD32X32V maxSD32SD32X(no fuse)IncomingtelephonelineModem,fax ortelephone456123Final output fromPLC,DCS,SCADAetc.110/120V acor220/240V acAnalogue outputsController outputs (I/P converters)F or this application, the recommendations are the SD16, SD32 and SD55 (and the equivalent ‘X’ versions), the final choice depending upon the operating voltage.Digital (on/off) inputsSwitchesSuitable SPDs for switches include the SD07, SD16, SD32 and SD55 modules – the choice depending upon the operating voltage of the system.

Generally the voltagesacross the pairs are similar and so therecommended choice would be a pair ofSD16X, SD32X or SD55Xs. However, mainspowered transmitters should be protected withan SD150X or 275X (depending upon supplyvoltage) for the supply inputs.Loadcells are catered for by MTL SurgeTechnologies’ LC30 which is suitable for both 4and 6-wire load cells.series makes it the obvious choice for transmitter protection.The SDs within the junction box should be installed no further than one metre away but as close as possible to the sensor or transmitter they are protecting. A bond is required from the general mass of steelwork to the sensor or transmitter housing either using a flat short braid or a cable of at least 4mm2cross sectional area. In most instances this bond is automatically made by fixing the metallic transmitter housing to the plant structure. This bond ensures the voltage difference between the signal conductors and the transmitter housing is below the transmitter’s insulation rating. Please note that the transmitters or sensors are connected to the ‘Protected Equipment’ terminals of the SD and not the ‘Field Cables’.456123456123456123456123TP48SD32R (no fuse)SD32R (no fuse)SD32R (no fuse)TP48Communication systems protectionHigh speed data links between buildings or one part of a plant to another have become more common with the widespread use of smart transmitters and the increase in unmanned installations. The SD series has an SPD suitable for all process I/O applications with a choice of low resistance units, high bandwidth and a variety of voltage variants. The SDR series has been specially designed to meet the requirements for high speed data links with an extremely high bandwidth.Communication systemsRS232, RS422, RS485The recommended choice for these applications is the SD16R or SD32R depending on the maximum driver signal.Bus powered systemsThere are a variety of bus powered systems specially designed for the process industry. The ideal surge protection device for these systems is the SD32R as it has a very high bandwidth and a modest in-line resistance.Typical ApplicationsTable 1 shows suitable SD devices for different applications. In some applications alternative devices may be used, for example, where lower in-line resistance or a higher voltage power supply is used.Telematic have operationally tested therecommended SD series with representative highways listed but no formal approval for their use in systems by the respective bodies has been sought.RS232, RS422, RS485Bus powered systemsTable 1TP PROTECTED FIELD CIRCUITSD PROTECTED HOST CIRCUITPROTECTED FIELD CIRCUITSD PROTECTED HOST CIRCUITApplicationPreferred SPDAlternativeAllen Bradley Data Highway Plus SD16RFoundation Fieldbus 31.25kbits/s voltage mode SD32R 1.0/2.5 Mbits/s SD55R HART SD32X SD32, SD32R Honeywell DE SD32XSD32, SD32RLonWorks FFT-10SD32R LPT-10SD55R TP-78SD07R IS78†SD32R Modbus ‘& Modbus Plus (RS485)SD16R PROFIBUS DPSD32R PA (IEC 1158, 31.25 kbits/s)SD32R RS232SD16SD16XRS422SD07R RS423SD07R RS485SD07R WorldRP (IEC 1158)SD32R31.25 kbits/s voltage mode 1.0/2.5 Mbits/sSD55RThe SDs should be mounted on the field wiring side to ensure that any surges entering from the field do not damage any intrinsically safe barriers or galvanic isolators in the system. The SDs and IS interfaces should be mounted close to each other but on separate DIN rails in order to maintain the required 50mm clearance between safe area and hazardous area terminals.EarthingThe recommended earthing for field mounted devices has been illustrated previously but it is the earthing at the control panel that is more critical as there are usually a number of earthing systems, each with their own requirements. The earthing system illustrated here replaces the instrument 0V bond, the control system PSU bond and the IS earth with one single earth connection to meet all the design requirements and give the most effective protection against the effects of lightning induced surges.Zone 0 are considered real enough to require preventative measures. IEC 60079-14 (1996-12) Electrical apparatus for explosive gas atmospheres Part 14: Electrical installations in hazardous areas (other than mines) stresses the importance of SPDs in hazardous areas. An outdoor installation where there is a high likelihood of both lightning induced transients and combustible gases requires the installation of SPDs to prevent possible ignition of the gases. Areas seen particularly at risk include flammable liquid storage tanks, effluent treatment plants, distillation columns in petrochemical works and gas pipelines.SPDs for transmitter protection should be installed in Zone 1 but sufficiently close to the Zone 0 boundary to prevent high voltages entering Zone 0. The distance from the SPD to Zone 0 should be less than one metre where possible. However, in practice the SPD would normally be mounted on the transmitter or sensor housing which usually lies in Zone 1and is very close to Zone 0. Because there is only a very small free volume, the SD Series is suitable for mounting in flameproof or explosion proof enclosures.Zone 2The SD series is suitable for protecting electrical circuits in Division 2, Zone 2 and can be used without affecting the safety aspects of the circuit.Non-incendive (low-current) circuits can be protected using any SD series unit mounted in either the safe or hazardous area including those with the fuse disconnect facility. Non arcing (high current) circuits can also be protected except that SPDs with the fuse disconnect facility may only be mounted in the safe area. F or use in these circuits the units must be mounted in a suitable enclosure, normally the minimum requirements are IP54 and 7Nm resistance to impact. The SD series is self certified by Telematic Ltd as being suitable for this purpose.CertificationIntroducing surge protection into Intrinsically Safe (IS) circuits is trouble free as long as the current and power parameters are not exceeded. In the SD Series, the SD**X, SD**R,SD**R3, SD RTD and SD**T3 all have ATEX certification for use in IS circuits located in Zones 0, 1 or 2. The certification parameters for the SD**X and SD**T3 are:EEx ia IIC T4, Li = 0.22mH Ii = 260mA for Ui up to 20V Ii = 175mA for Ui up to 26V Ii = 140mA for Ui up to 28V Ii = 65mA for Ui up to 60VThe certification parameters for the SD**R,SD**R3 and SD RTD are:EEx ia IIC T4, Li = 0Ii = 260mA for Ui up to 60VThe power rating for each of the above is dependent on the table shown below.Pi = 1W (–30°C to +75°C)Pi = 1.2W (–30°C to +60°C) Pi = 1.3W (–30°C to +40°C) The SD** Series are classifed as simple apparatus and are intended for use in Zone 2 or safe areas only, because their fuses are not fully encapsulated.SD Series mounting kits and accessories The SD Series has a full range of mounting kits and accessories to simplify installation and tagging of individual loops. Insulating spacers (ISP7000) are available to allow mounting of the units onto backplanes without compromising correct earthing practice.These are placed at regular intervals along the rail or at each end as required. Earth connections can be made to the DIN rail via the earth terminal (ETL7000). Weatherproof enclosures are also available with all the necessary mounting accessories to install the SD series surge protection devices.Two tagging systems are available. One consists of tagging strips (TAG57) with labels (TGL57) mounted on posts (IMB57) at each end of a row of surge protection devices (SPDs). The other consists of separate tagging identifiers (BRI7000) mounted on the tops of individual SPDs. Both methods can be used conjointly. Replaceable fuses or solid links are available in packs of 5 (SD-F25, SD-F05 and SD-LNK). 7BRI700012BIL7000/BIL7000LSpecification(all figures typical at 25°C unless otherwise stated)Note: all figures are typical at +25°C unless otherwise stated; *standard fuse; +over full working temperature range; †at 20mA with a 250mA standard fuse; ‡these units need external 3A fuses; ^Signal; **Power & Common; maximum energising current depends upon RTD resistance.ProtectionFull hybrid line to lineEach line to screen/groundNominal discharge surge current (I n )10kA (8/20µs),(not applicable to SD150X and SD275X)Nominal discharge surge current (I n )6.5kA (8/20µs),(SD150X and SD275X only)Reaction time (T a )Within nanoseconds (10–9s)RTD resistance range (SD RTD )10 to 1500ΩDegradation accuracy (SD RTD at 1mA)0.1% (RTD resistance >100Ω)0.1Ω(RTD resistance < 100Ω)Ambient temperature–30°C to +75°C (working)–40°C to +80°C (storage)Humidity5 to 95% RH (non-condensing)Terminals2.5mm 2(12 AWG)MountingT-section DIN-rail(35 x 7.5 or 35 x 15mm rail)Weight70g approximately Case flammability UL94 V-2EMC complianceTo Generic Immunity Standards, EN 50082, part 2 for industrial environments R&TTE complianceEN 50082-2 : 1995EN 41003 : 1999EN 60950 : 1992(not applicable to SD150X and SD275X)LVD complianceSD150X & SD275X EN 60950 : 1992EN 61010 : 1995SD PSTNEN 41003 : 1999IEC complianceEN 61643-21:2001To order specify -Order by module, as listed in the specification table and/or accessory part numbers as defined on page 7.Note: In accordance with our policy of continuous improvement,we reserve the right to change the product’s specification without notice.Definitions of terminology used in table 1Working voltage (U n )Maximum voltage between lines or lines/ground for the specified leakage current 2Maximum leakage current (I c )Maximum current drawn by the SPD at the。
