GE Fanuc IC693PWR332

The IC693PWR332 is a robust High Capacity Power Supply designed specifically for the GE Fanuc Series 90-30 Programmable Logic Controllers (PLCs). This power supply features a nominal input of 12 VDC, accommodating a voltage range from 9.6 to 15 VDC, and offers a total load capacity of 30 Watts. It provides multiple outputs: a +5 VDC output, tailored for CPU inputs and outputs; a +24 V Relay output suited for relay modules; and an isolated +24 VDC supply for both internal and external module use. The user terminal strip includes connections for DC input, system ground, and the +24 VDC output necessary for I/O modules.

This unit is equipped with a CPU RS-485 serial port, allowing connectivity to a computer, handheld programmer, or other serial devices. Internal connections involve +24 VDC isolated and relay connections alongside the +5 VDC and ground pathways. To determine the appropriate input power for the IC693PWR332, one must calculate the sum of the required power from all modules, multiply that total by 1.5, and divide by the source voltage for current values. The power supply includes four LED indicators: the PWR LED illuminates green when the unit receives adequate power, the OK LED signals proper PLC operation, the RUN LED shows the PLC is active, and the BATT LED turns red to indicate a low backup lithium battery, crucial for retaining data during power outages. The battery is replaceable even while the unit is powered on, accessible by removing a plastic cover on the faceplate. The IC693PWR332 typically occupies the leftmost slot on baseplates and operates with a communication standard of RS-485.
