I/O modules

Product Overview

The GE IC695PSA040 functions as a universal base power supply for the PACSystem RX3i automation platform from GE Fanuc and Emerson Automation. This module provides reliable DC power to the backplane and connected I/O modules in industrial control applications. We engineered the IC695PSA040 to deliver stable, isolated power for demanding automation environments worldwide.

Technical Specifications

Key Features and Benefits

• Universal AC/DC Input: The IC695PSA040 accepts both AC and DC input voltages over a wide range. You therefore use the same power supply in facilities with different power systems without modification.

• Triple Output Voltages: This module provides +5.1 VDC for logic circuits, +24 VDC for relay outputs, and +3.3 VDC for internal use. Consequently, it powers all RX3i module types from a single supply unit.

• High Isolation for Safety: Input-to-backplane isolation of 250 VAC continuous protects sensitive electronics. This isolation exceeds industrial standards for safe operation in control panels.

• Visual Status Indication: Front-panel LEDs show power OK and fault conditions at a glance. You quickly verify proper operation during startup and troubleshooting.

• Redundancy Capable: You install up to four power supplies in a single rack for redundant configurations. Therefore, critical applications continue operating even if one supply fails.

Detailed Functional Description

The primary function of the GE IC695PSA040 involves converting incoming AC or DC power into the regulated DC voltages required by RX3i modules. Specifically, it plugs into the leftmost slots of a universal backplane and distributes power through the bus connectors. The +5.1 VDC supply powers all module logic circuits, while the +24 VDC supply provides power for relay outputs and field-side circuits. The +3.3 VDC output supports internal processor requirements. The module includes filtering and regulation to ensure clean, stable power for reliable PLC operation.
