GE IC693PWR321AA Power Supply Module for Series 90-30 PLCs

The GE IC693PWR321AA provides stable DC power to Series 90-30 PLC racks. You can install this module into the dedicated power slot of any 90-30 base. It converts 115 V AC or 230 V AC into regulated 24 V DC and 5 V DC outputs. This unit supports CPUs, I/O modules, and communication cards reliably.

Technical Specifications and Hardware Configuration

This power supply module measures 127 mm in height. Its width reaches 55 mm, and the depth equals 140 mm. The GE IC693PWR321AA weighs approximately 0.62 kilograms. A single internal PCB carries all rectification, filtering, and regulation circuits. The module contains three electrolytic capacitors for bulk energy storage. These capacitors provide 30 milliseconds of hold-up time during input dips. One 3-pin screw terminal block accepts AC input wiring. A dedicated 8-pin connector delivers DC outputs to the backplane.

Electrical Ratings and Performance Characteristics

The GE IC693PWR321AA accepts input voltages from 85 V AC to 264 V AC. It operates at line frequencies of 47 Hz to 63 Hz automatically. This module delivers a nominal output of 5 V DC at 6 A continuously. It also provides 24 V DC at 1 A for output modules. Output ripple stays below 35 mV peak-to-peak at full load. Efficiency reaches 82 percent under typical operating conditions. Consequently, this unit generates moderate heat inside the cabinet. Overvoltage protection clamps the outputs at safe levels. Short-circuit protection safely shuts down individual outputs during wiring faults.

Installation and Operational Guidelines

You must slide this module into the leftmost slot of the 90-30 rack. Transitioning to wiring, use 1.5 mm² stranded wire for the AC terminals. A green front LED indicates normal output voltage presence. The module requires 40 mm of free space above and below for airflow. For safety, disconnect mains power before removing the unit. The operating temperature range sits between 0°C and 60°C reliably.
