D3-15Model CIO-PDISO16$549ߜ16 Electromechanical Relay Outputsߜ16 Isolated Digital Inputs (500 V Isolation)ߜDigital Inputs Accept AC or DC SignalsProviding 16 electromechanical relays for output actuation and 16 isolated inputs (500 V), the CIO-PDISO16board is a low cost, low profile way to monitor and control high voltage AC or DC directly from your personal computer.The 16 relays are addressed as two 8-bit ports. Ten relays are form C SPDT and 6 are form A normally open. The contacts are rated at 5 A at 120 Vac or 6 A @ 28 Vdc with resistive load. The 16 isolated inputs are also addressed as two bytes.The inputs are not polarity sensitive and may be mixed between 5-24 Vac (50-1000 Hz) and 5-24 Vac (not TTL compatible). Although the connector is a 50-pin header, it maps directly to a 37-pin through the BP40-37 for customers who want to maintain a strict CIO-PDISO8 configuration.Software SupportThe CIO-PDISO16 is supplied with InstaCal software for configuration and testing. In addition, it is also supported by the optional Universal Library. The Universal Library is aset of I/O libraries and drivers for users creating their own custom programs. The Universal Library is compatible with most DOS and Windows (16-bit and 32-bit) based languages (DLL and VXD) and supports the entire CIO family of boards. An optional driver for LabVIEW is also available. Icon driven control programs such as LabtechNotebook, Labtech Control and Dasylab support the CIO-PDISO16.SpecificationsRELAY OUTPUTSQuantity: 16 total; 10 are Form C and 6 are Form A normally open Contact Rating: 28 Vdc @ 6 A, 120Vac @ 5 AContact Type: Gold overlay silverContact Resistance: 100 ΜΩmax Operating Time: 20 msec Release Time: 10 msecLife: 10 million operations, minimum ISOLATED INPUTSQuantity: 16 Opto-isolated,non-polarized.

Matte Tin Lead Finish
Matte tin has become the industry standard lead-free replacement for SnPb lead finishes. A matte tin finish is composed of 100% tin solder with large grains. Since the solder volume on the leads is small compared to the solder paste volume that is placed on the land pattern of the PCB, the reflow profile will be determined by the requirements of the solder paste. Therefore, these devices are compatible with both lead-free and SnPb assembly techniques. In addition, unlike other lead-free compositions, matte tin does not have any added alloys that can cause degradation of the solder joint.

PROTECTION PRODUCTS Applications Information
Device Connection for Protection of One Data Line
Good circuit board layout is critical for the suppression of fast rise-time transients such as ESD. The following guidelines are recommended:
z Place the SDC15 near the input terminals or connectors to restrict transient coupling.
TVS diodes are characterized by their high surge capability, low operating and clamping voltages, and fast response time. This makes them ideal for use as board level protection of sensitive semiconductor components. The dual-junction common-cathode design allows the user to protect one data or power line operating at ±12 volts. The low profile SOT23 package allows flexibility in the design of “crowded” circuit boards.
