GE Fanuc IC695PSA140B PACSystems RX3i Multi-Purpose Power Supply Module
Configured for internal DC voltage regulation and backplane current distribution in PACSystems RX3i Universal Backplane systems, the GE Fanuc IC695PSA140B (IC695PSA140 Multi-Purpose Power Supply Module) provides direct physical/electrical execution. The module converts incoming AC or DC supply feeds into regulated output rails of 3.3 VDC, 5.1 VDC, and 24 VDC to energize local I/O modules and option cards. Operating at a 40 W total load capacity, the hardware installs into two slots of an IC695 series universal backplane with support for parallel load sharing and redundant configurations.

Backplane Bus Power Distribution & Firmware Compatibility
The module interfaces directly with the PACSystems RX3i universal backplane high-speed bus to supply steady direct current logic power across all occupied expansion slots. Firmware flash compatibility within the RX3i CPU platform enables real-time reporting of power supply health indicators, including overtemperature thresholds and current overload states, via system status registers. Integrated internal circuitry enables auto-balancing load distribution when installed alongside a second IC695PSA140 module in a dual-power universal rack.
Frequently Asked Questions
Q: Does the IC695PSA140B support parallel operation for redundant power configurations?
A: Yes, two IC695PSA140B modules installed on the same IC695 universal backplane execute active load sharing, enabling power redundancy if one supply fails.
Q: What wire gauge range is permitted for connection to the input power terminal block?
A: The input screw terminals accept 14 AWG to 22 AWG solid or stranded copper wire, limited to one wire per terminal with a maximum current rating of 6 A per point.
Q: What indicates an internal overtemperature or current overload condition?
A: Front panel diagnostic LEDs indicate module states; dedicated lights illuminate for Overload and Overtemperature conditions while forcing the P/S Fault indicator active.
Field Installation Guidelines
De-energize the main AC or DC line power before inserting or removing the module from the RX3i universal backplane chassis. Align the double-width card edges with the backplane guides in the designated power supply slots and press firmly until the module latches sit securely.
Strip input power wiring to standard length and secure 14 AWG to 22 AWG conductors into the terminal block. Maintain dedicated earth ground wiring from the ground terminal directly to the enclosure grounding bar to comply with the 1500 VAC input-to-backplane continuous isolation specifications. Ensure surrounding rack clearance maintains natural convection airflow to keep operating temperatures between 0 and +60 deg C without fan assistance.
