Offset ranges such as 1-5 VDC and 4-20 mADC are also included.Heavy-duty relay contacts allow the module to directly control high capacity loads. F ront-accessible potentiometers are used to adjust the alarm setpoint from 0 to 100% and the deadband from 1 to 100%.The DMD1080 provides a single setpoint adjustment of the two DPST relay contacts. The alarm output can be field configured for HI or LO operation, latching or non-latching, and normal or reverse acting. Deadband control can be adjusted from 1 to 100% and the alarm setpoint from 0 to 100%.Sink/Source Input and Loop SupplyFor maximum versatility, a current input can be selectively wired for sinking or sourcing. This allows the DMD1080 to work with powered or unpowered mA inputs. A regulated 15 VDC loop excitation supply can be used to power passive input devices eliminating the need for an additional DC loop supply.Input and Alarm Status LEDsThe input LED varies in intensity with changes in the process input signal. A red/green bi-color alarm status LED visually indicate alarm status. These LEDs provide a quick visual status of your process at all times.Output Test / UnlatchA functional test button can be used to verify the alarm and system operation and also provides the additional function of unlatching the alarm when the latching mode has been selected.The output test button greatly aids in saving time during initial startup and/or troubleshooting.S w i t c h i n g C u r r e n t (A )Switching Voltage (V)Relay Contact Ratingse-mail:**************For latest product manuals:Shop online at User’s GuideWARNING: This product can expose you to chemicals includ-ing nickel, which are known to the State of California to cause cancer or birth defects or other reproductive harm. For more information go to Range SelectionIt is generally easier to select ranges before installation. See the model/serial number label for module information, options, or if a custom range was specified.Set input selector switch A to “I” for a current input or to “V” for a voltage input.Switch settings B and C determine the input range. Switch D determines the alarm configuration.Electrical ConnectionsWARNING! All wiring must be performed by a qualified electri-cian or instrumentation engineer. See diagrams for terminal designations and wiring examples.Avoid shock hazards! Turn power off to signal input, relay wiring, and module power before connecting or disconnecting wiring.Module Power TerminalsCheck white model/serial number label for module operating voltage to make sure it matches available power.When using DC power, either polarity is acceptable, but for consistency with similar products, positive (+) can be wired to terminal 13 and negative (–) can be wired to terminal 16. Signal Input TerminalsPolarity must be observed for input wiring connections. If the input does not function, check switch settings and wiring polarity.Voltage inputs are connected as shown in the table below.The input can be used with either sinking or sourcing milliamp devices. Only one device must provide power to the current loop.For a transmitter with a current output, determine if it provides power to the current loop or if it must be powered by the DMD 1080 module. Use a multi-meter to check for voltage at the transmitter’s output terminals. Typical voltage may be in the range of 9 to 24 VDC. In this case, wire the device to terminals 9 and 11.Relay Output TerminalsSee wiring diagrams for connections. The module does not provide power to the relay contacts.Inductive loads (motors, solenoids, contactors, etc.) will greatly shorten relay contact life unless an appropriate RC snubber is installed.The DMD1080 operates two sets of relays in unison with a single setpoint.The dual DPST contact sets are in a Form A (NO) and a Form B (NC) configuration.They may be field wired for Form C operation as required.Form A Form BJumper 2 & 3 for Form C operation Jumper 6 & 7 for Form C operationTest: Push to toggle relays to oppo-site stateInput LED : Variable brightness green LED indicates input level Bi-Color Alarm LEDGreen = non-alarm condition Red = alarm conditionDeadband: Smaller = counterclock-wise.

Allow 1” (25 mm) above and below hous-ing vents for air circulation.PrecautionsWARNING! Avoid shock hazards! Turn signal input, output, and power off before connecting or disconnecting wiring, or remov-ing or installing module.Installation1. Tilt front of module downward and position the lower mounts and spring clips against the bottom edge of DIN rail.2. Clip Lower Mount to bottom edge of DIN rail.3. Push front of module upward until upper mount snaps into place.Removal1. Push up on bottom back of module.2. Tilt front of module downward to release upper mount from top edge of DIN rail.3.The module can now be removed from the DIN rail.Setup and CalibrationThe input ranges are factory calibrated and do not require adjustment.The Setpoint potentiometer allows the operator to adjust the level at which the alarm is activated. This control is adjustable from 0 to 100% of the input range.The Deadband potentiometer allows the alarm trip and reset window to be adjusted symmetrically about the setpoint from 1 to 100% of the span. This allows the operator to fine tune the point at which the alarm trips and resets.The deadband is typically used to prevent chattering of the relays or false trips when the process signal is unstable or changes rapidly.To calibrate the alarm section, set the deadband control to the minimum (counterclockwise).Set the signal source to a reference that represents the desired trip point.Adjust the setpoint control to the point at which the relay chang-es state form a non-alarm to an alarm condition. The deadband will be 1.0% of span in this case.If a larger amount of deadband is desired turn the deadband potentiometer clockwise. The deadband is symmetrical about the setpoint; both transition points will change as deadband is increased.Output Test FunctionWhen the test button is depressed it will drive the relays to their opposite state. This can be used as a diagnostic aid during initial start-up or troubleshooting. When released, the relays will return to their prior states.OperationThe green input LED provides a visual indication that a signal is being sensed by the input circuitry of the module. It also indicates the input signal strength by changing in intensity as the process changes from minimum to maximum.If the LED fails to illuminate, or fails to change in intensity as the process changes, check the module power or signal input wiring. Note that it may be difficult to see the LEDs under bright lighting conditions.The bi-color alarm LED provides a visual indication of the alarm status. In all configurations, a green LED indicates a non-alarm condition and a red LED indicates an alarm condition.In the normal mode of operation, the relay coil is energized in a non-alarm condition and de-energized in an alarm condition. This will create an alarm condition if the module loses power.For a normal acting, non-latching configuration, the alarm will activate when the input signal exceeds the setpoint (HI alarm) or falls below the setpoint (LO alarm), then will automatically reset when the alarm condition no longer exists.For a reverse acting alarm, the relay coil is de-energized in a non-alarm condition and energized in an alarm condition. The alarm activates when the input signal exceeds the setpoint (HI alarm) or falls below the setpoint (LO alarm), then automatically resets when the alarm condition no longer exists.When the latching mode is selected, it will be necessary to push the functional test button or remove power from the module to reset the alarm. The alarm will only reset if the alarm condition no longer exists.OMEGA’s policy is to make running changes, not model changes, whenever an improvement is possible.

运行状态说明
◇正常运行时，绿灯常亮：
设备上电后，当设备正常工作时，绿色指示灯常亮，D-Sub9接口的第3脚和第8脚导通。
◇电流过载或供电异常时，绿灯熄灭：
当绿灯不亮时，应该首先检查传感器的供电电源是否正常。
在供电电源正常的情况下，如果绿色指示灯熄灭，说明电流传感器处于非零磁通状态。
此时若母线输入电流幅值超过传感器的规定量程，传感器进入过载工作模式，输出电流不再与输入电流信号成等比例。
在过载模式下，传感器输出电流一直保持在最大输出状态，绿色指示灯熄灭。
当输入电流恢复到规定被测电流范围内后，传感器输出电流恢复正常，绿色指示灯常亮。
◇在过载模式下，D-Sub9接口的第3脚和第8脚断开连接。
