Description Reviews

The GE IC695PSA040, also cataloged as the IC695PSA040 Multi-Purpose Power Supply Module, operates as a dedicated hardware component for power conversion and load distribution within PACSystems RX3i platforms. This component provides an output power rating of 40 Watts, delivering stabilized internal system voltages (+5.1 VDC and +3.3 VDC) directly to the RX3i universal backplane bus while providing an auxiliary isolated +24 VDC output loop for external relay circuitry. The module accommodates both universal alternating current (AC) and direct current (DC) power sources within a single physical slot footprint.

Backplane Bus Communication Velocity & Firmware Integration

The IC695PSA040 mounts directly into the RX3i Universal Backplane, establishing physical interface pathways with the high-speed PCI bus. While it does not require backplane bus communication velocity licences, the power supply contains internal sensor circuitry which interacts with the master controller to report status flags. This firmware integration enables real-time diagnostic reporting to the CPU regarding voltage dips, thermal limits, or load anomalies. The module is fully compatible with dynamic I/O density scaling setups where up to four power supply units can be installed per IC695 rack, subject to slot availability and backplane segmentation configurations.

Frequently Asked Questions

Q: Can multiple IC695PSA040 power supplies be wired in parallel for redundancy or increased capacity in the same backplane?

A: No. The IC695PSA040 does not support increased capacity or load-sharing redundancy. It cannot be mixed with other RX3i power supplies residing in the same backplane segment. If total module power demand exceeds 40 Watts, excess modules must be moved to an expansion baseplate powered by a separate supply unit.

Q: Does the front-panel ON/OFF switch disconnect the incoming field power?

A: No. The front-panel slide switch behind the hinged door only enables or disables the power supply outputs to the backplane. It does not isolate or cut off the incoming 120/240 VAC or 125 VDC field line power. External disconnects must be used for electrical isolation.

Q: What do the four LED indicators represent on the front faceplate?

A: The indicators display system status: Power (green when output voltages are within limits), P/S Fault (red during internal hardware failures), Over Temperature (red if the internal heatsink exceeds safe operating thermal limits), and Overload (red if output current limits are exceeded).

Field Installation Guidelines

Backplane Insertion: Turn off all incoming power before physical installation. Slide the module vertically into the dedicated slot of the RX3i Universal Backplane, ensuring the locking tabs click securely into place.
Input Power Terminal Connections: Terminate the input wiring (Line, Neutral, and Ground for AC; positive, negative, and ground for DC) using 14 AWG to 22 AWG field conductors. Maximize terminal tightness without exceeding torque specifications.
External Disconnect: Install a double-pole branch-circuit breaker or a fused disconnect switch in the incoming power line to allow safe isolation during field maintenance procedures.
Grounding: A low-impedance connection from the module ground terminal to the system protective earth (PE) bus is mandatory. Ground connections must not exceed 0.1 Ohms resistance.
