GE Fanuc Emerson IC693PWR321N Series 90-30 Standard Power Supply

The GE Fanuc Emerson IC693PWR321N is a standard power supply module designed for the Series 90-30 PLC platform. It occupies the leftmost slot of the baseplate and delivers a total output power of 30 watts to support system processing and field circuit requirements. This unit accommodates versatile AC and DC input sources while providing enhanced diagnostic tracking and short-circuit hardware protection.

Input and Power Ratings

The power supply operates across a wide AC input range of 85 to 264 VAC or a DC input range of 100 to 300 VDC. It requires an input power of 90 VA for AC configurations or 50 W for DC setups. During startup, the module manages an inrush current of 4 A peak for a maximum duration of 250 milliseconds.

Output Rails and Protection Features

The module supplies three independent voltage outputs: 5 VDC at up to 15 watts, 24 VDC relay power up to 15 watts, and an isolated 24 VDC supply up to 20 watts. Built-in protection mechanisms include overvoltage limits between 6.4 VDC and 7 VDC, maximum 4 A overcurrent protection, and a minimum holdup time of 20 milliseconds.

Communication and Hardware Design

An integrated 9-pin sub-D RS-485 serial port allows direct connection to central processing units and external peripheral devices. The hardware architecture incorporates a smart switch fusing mechanism and an internal replaceable fuse. The module is certified for cULus and CE standards and is rated for Class 1 Division 2 hazardous locations.

Installation Guidelines

The power supply module must be installed directly into the leftmost slot of the Series 90-30 baseplate. Ensure the system power is completely disconnected before inserting or removing the module. Secure the unit properly and verify all field wiring connections to the six available terminals before re-applying AC or DC source power.
