GE IC693PWR322E Power Supply Module

Power Delivery and Electrical Specifications

The GE IC693PWR322E supplies reliable DC power to the Series 90-30 programmable controller system. It accepts a wide input range of 85 to 264 VAC or 100 to 300 VDC, providing flexibility for global installations. This module delivers 30 Watts of output power across 5 VDC and 24 VDC output rails. It supports backplane loads of up to 30 Watts while supplying isolated 24 VDC power for input devices and field circuits.

This power supply features overvoltage protection and short-circuit protection to safeguard connected modules. It automatically recovers from fault conditions without requiring manual intervention. Therefore, engineers can rely on this unit for continuous operation in demanding industrial environments.

Physical Characteristics and Installation

The IC693PWR322E measures 13.0 cm in height, 5.5 cm in width, and 12.8 cm in depth. It weighs approximately 0.7 kg, allowing for easy handling during installation. This module occupies the leftmost slot of the Series 90-30 baseplate, where it interfaces directly with the backplane power bus. The front panel includes LED indicators for power status and module health. These visual indicators provide immediate confirmation of proper operation.

A removable terminal block accommodates field wiring for AC or DC input connections. This terminal block accepts wire sizes from 0.2 to 2.5 mm² (24 to 14 AWG). The unit also provides terminals for external 24 VDC output to power sensors and other field devices.

Energy Storage and Hold-Up Capability

This power supply incorporates energy storage capacitors that maintain output during brief AC power interruptions. It provides a hold-up time of approximately 20 milliseconds at full load after losing input power. This feature allows the CPU and I/O modules to complete critical operations before shutdown. The capacitors also filter incoming power, reducing ripple and noise on the DC output rails.
