GE IC695PSD140B Power Supply Module: Reliable Power for PLC Systems

Introduction

Walking through most factory floors, you rarely notice power supply modules—but they quietly do the work that keeps PLC systems alive. The GE IC695PSD140B Power Supply Module is one of those unassuming but critical pieces. On robotic lines, packaging machinery, or water treatment panels, it keeps systems running and protects electronics, making sure production doesn’t skip a beat.

Performance and Technical Features

I’ve installed the IC695PSD140B on several PACSystems RX3i backplanes, and GE IC695PSD140B’s straightforward to see why engineers trust it. It takes 18–30 V DC input and provides three outputs: +5.1V, +24V, and +3.3V, with a total output power of 40W. The output currents—6A for 5.1V, 1.6A for 24V, and 9A for 3.3V—cover the needs of logic circuits, relays, and sensors in most PLC systems.

One feature I’ve found particularly useful is its overcurrent and overload protection. On one production line, a sensor shorted and a load spiked, but the PLC system kept running without a hitch. In critical sections, we sometimes install four IC695PSD140B modules in parallel. That redundancy makes sure continuous operation is maintained even if one module fails.
