The GE Fanuc IC693MDL655 is a 24-volt DC Positive/Negative Logic Input module specifically designed for compatibility with the Series 90-30 Programmable Logic Controller. This module features 32 discrete input points organized into four groups of eight, with each group offering isolation and a shared common among its points. The input points can operate within a voltage range of 0 to 30 volts DC and are adaptable to both positive and negative logic configurations. Enhanced system reliability is ensured through the inclusion of opto-couplers that provide backplane isolation between the field and logic sides, in addition to the isolation between individual input groups. A visual LED block on the front panel includes ON/OFF status indicators for each of the 32 inputs, facilitating easy monitoring of input statuses. For user convenience, the module can supply a 24 VDC output for field devices through its I/O connectors and is fully compatible with any I/O slot in the Series 90-30 PLC baseplate. It features two male 24-pin connectors for connecting user input devices, allowing for group A and B connections through the right connector, while the left connector accommodates groups C and D. To facilitate the connection of field devices, users can employ cables with tinned wires on one end and a mating female connector on the other, with compatible part numbers IC693CBL327 and IC693CBL328 available for purchase. The IC693MDL655 supports a rated input current of 7.0 mA and operates effectively at temperatures ranging from 32°F to 140°F.
