GE Fanuc IC694MDL645

The IC694MDL645 is a 16-point positive/negative logic input module from GE Fanuc's RX3i PACSystems series. This low-voltage module operates at a nominal voltage of 24 volts DC and can accommodate input voltages ranging from 0 to 30 volts DC. It features a single group of 16 discrete input points, all sharing a common power input terminal, and does not impose any backplane restrictions. The module is versatile, allowing for wiring in either positive or negative logic configurations, and includes 16 LED indicators that visually confirm the ON/OFF status of each input point. Compatible with a variety of external input devices—including switches, buttons, and BCD thumbwheels—the IC694MDL645 facilitates seamless interaction between these devices and the PLC, as well as connections to external output modules like relays and contactors. This input module is easily installed in any slot of the RX3i system and supports hot swapping; however, the field side terminal block must be detached during insertion or removal while the system is powered. Rated for an input current of 7 mA and a power consumption of 80 mA from the 5V bus and 125 mA from the 24V supply, the IC694MDL645 is characterized by the blue bands on its label, indicating its low-voltage designation. With the extensive range of GE Fanuc I/O modules available, users can find suitable solutions for diverse applications and requirements.
