The IC693PWR321 module is a power supply module manufactured by GE Fanuc Automation as part of Series 90-30. It is used to provide power for the applications handled by the Series 90-30 PLCs. This unit is placed in the leftmost slot of the PLC baseplate. It operates with a power rating of 30 Watts, and it supports AC as well as DC power supplies. This power supply comes with an operating voltage range of 85 to 264 Volts AC and 100 to 300 Volts DC. The IC693PWR321 power supply has 3 output voltage ratings including 24 Volts DC and 5 Volts DC regular voltage, and 24 Volts DC of isolated voltage. The output voltage powers the different circuits while the isolated voltage is intended for special modules that provide the external power. The inrush current of this module is 4 Amps at peak, for a maximum of 250 milliseconds. This power supply is a programmable controller which features a robust build and also comes with a battery for backup.
