GE IC694PWR321B Universal Power Supply Module
The IC694PWR321B is a high-performance universal power supply module engineered for GE RX3i PACSystems in industrial automation applications. This module accepts wide-range AC or DC input voltages, converting them into stable, regulated DC power rails to reliably drive PLC backplanes and field instrumentation. Built with comprehensive electrical protections, it mounts directly into the dedicated leftmost slot of the RX3i backplane.
Power Output and Regulation Performance
The power supply delivers multiple voltage outputs, including a regulated 5 VDC rail (5.0–5.2 V) providing up to 5 A of backplane current, a 24 VDC relay power supply (24–28 V), and a 24 VDC isolated output. Total available output power scales depending on 5 VDC load usage, providing up to 30 W when the 5 VDC rail is unpopulated or up to 15 W when active. Voltage stability is maintained through tight load regulation of ±3% and line regulation of ±1%, with peak-to-peak ripple and noise restricted to under 1%.
Protection Features and Thermal Management
To safeguard industrial control systems against electrical faults, the unit integrates built-in overcurrent, overvoltage, and short-circuit protection mechanisms. Thermal dissipation relies entirely on natural convection cooling without requiring external fans. The module operates reliably in ambient temperatures ranging from 0 deg C to 60 deg C and withstands relative humidity levels between 5% and 95% non-condensing.

Installation Guidelines
The IC694PWR321B module must be installed in the leftmost slot of the RX3i backplane, as this slot is specifically wired to distribute power across the system bus. Ensure input power wiring is completely de-energized before connecting AC or DC lines to the module terminals. Verify proper grounding connections to the backplane chassis to ensure compliance with EMC standards.
