General Electric IC695PSA040 Power Supply

The GE IC695PSA040 is a high-reliability 40-watt power supply designed for the PACSystems RX3i automation platform. This module provides essential operational energy to the CPU and connected I/O components. Because it supports a wide input range, it operates globally on various AC and DC power standards. The unit converts high-voltage inputs into three distinct regulated outputs. It serves as a foundational component for stable control system performance in industrial environments.

Multi-Rail Power Distribution

This power supply effectively manages three critical voltage rails for the universal backplane. The +3.3 VDC and +5.1 VDC outputs drive the internal logic of the system modules. Meanwhile, the +24 VDC output provides power specifically for relay circuits and external field devices. Furthermore, the internal circuitry maintains high signal purity for sensitive logic components. This clean power delivery helps prevent data corruption across the RX3i backplane segment.

Diagnostic Monitoring and Safety

The hardware includes four front-facing LED indicators for real-time status monitoring. These lights notify technicians of power health, hardware faults, over-temperature events, and overload conditions. Additionally, a dedicated ON/OFF switch resides behind a protective hinged door for safe access. A special locking tab prevents the switch from toggling during accidental contact. However, users must remember that this switch only disables the output power rails. High voltage remains present at the input terminals even when the switch is off.

System Configuration and Compatibility

The IC695PSA040 fits perfectly into any RX3i universal backplane slot. Engineers must use this specific model in non-redundant configurations only. Because the module does not support load sharing, it cannot reside with other power supplies. If power requirements exceed 40 watts, users must move modules to expansion bases. This design approach ensures predictable power distribution for dedicated control setups.
