Product Details
The 24 VDC Positive/Negative Input Module (IC670MDL640) provides a single group of 16 discrete inputs, which may be driven by positive or negative logic. Intelligent processing for this module is performed by the Bus Interface Unit or elsewhere in the system. This includes configuring features such as input defaults and fault reporting. The module has 16 bits (two bytes) of discrete input data. A Bus Interface Unit is required to provide this input data to the host and/or local processor.
Power Sources： The module receives power from the Field Processor to run its own 5–volt logic. An external 24VDC supply is needed to power the input devices.
LEDs： Individual LEDs (logic side), visible through the transparent portion of the module top, indicate the on/off status of each input. The PWR LED is on when field and backplane power are present.
Field Wiring： The following illustration shows terminal assignments for the 24 VDC Positive/Negative Input Module.
Connection to the A terminals (marked NC in the diagram above) is optional. The Terminal Block with box terminals has 25 terminals for each module, each of which accommodates one AWG #14 (avg 2.1mm2 cross section) to AWG #22 (avg 0.36mm2 cross section) wire, or two wires up to AWG #18 (avg. 0.86mm2 cross section). When an external jumper is used, the wire capacity is reduced from AWG #14 (2.10mm2) to AWG #16 (1.32mm2).
The I/O Terminal Block with barrier terminals has 18 terminals per module. Each terminal can accommodate one or two wires up to AWG #14 (avg 2.1mm2 cross section).
The I/O Terminal Block with Connectors has one 20-pin male connector per module. The mating connector is the Amp part number 178289–8. Any tin-plated contact in the AMP D–3000 series can be used with the connector (Amp part number 1–175217–5 for high contact force receptacle for 20–24 gauge (0.20–0.56mm2) wires), 1–175218–5 for high contact force receptacle for 16–20 gauge (0.56–1.42mm2)).
