Procure now IC695PSA140 GE Fanuc PACSystems RX3i Power Supply
Procure now IC695PSA140 to deliver uncompromising, heavily regulated electrical power to the most advanced control architecture on your factory floor. The GE Fanuc IC695PSA140 is an industrial-grade, multi-purpose Power Supply Module meticulously engineered for the PACSystems RX3i Universal Backplane. Accepting a wide-ranging universal input of either 120/240 VAC or 125 VDC, this highly versatile 40-Watt unit is responsible for converting raw facility power into the three distinct DC voltage rails required by the RX3i ecosystem: +3.3 VDC for the high-speed PCI Express communication bus, +5 VDC for the traditional serial logic bus, and an isolated +24 VDC supply for relay output modules. Designed to withstand extreme voltage fluctuations, massive harmonic distortion, and the thermal stress inherent to enclosed control cabinets, the IC695PSA140 acts as a literal shield for your expensive CPUs and networking cards. Securing this genuine OEM component guarantees that your critical PLC backplane remains energized, stable, and completely protected against catastrophic electrical transients that could otherwise induce logic faults or wipe volatile memory registers.

Expert Backplane Loading and Installation Advice
When engineering an RX3i control panel, proper load calculation for the IC695PSA140 is an absolute necessity. While the unit provides 40 Watts of total power, you cannot draw the maximum rated wattage from the 3.3V and 5V rails simultaneously. High-speed PROFINET controllers and modern CPE-series processors draw heavily from the 3.3 VDC PCI Express bus. Before finalizing your hardware layout, meticulously calculate the current draw of all installed modules to ensure neither the individual rail limits nor the 40W total limit is exceeded. Overloading the backplane will trigger the power supply’s internal foldback protection, instantly shutting down the rack and halting your manufacturing process. Furthermore, this multi-purpose power supply occupies two physical slots on the universal backplane. It is standard industrial practice to install the power supply in Slot 0 (the far-left position) to ensure optimal power distribution trace routing across the high-speed VME connectors.
Frequently Asked Questions (FAQs)
Can I install two IC695PSA140 modules in the same rack for redundancy? No. While the RX3i platform supports specific redundant power supply architectures, the IC695PSA140 is designed strictly as a multi-purpose, standalone simplex power supply. If you require true load-sharing redundancy within a single backplane, you must utilize the specialized IC695PSD040 or similar redundant-capable modules.
What does it mean if the green ‘OK’ LED is off but the ‘Power’ LED is on? This specific LED state indicates that raw input power is reaching the module, but the internal circuitry has detected a critical fault—either an overvoltage condition, an overloaded backplane shorting out a DC rail, or a failure of the internal transformer. You must remove all I/O modules to test if the backplane is shorted; if the OK light remains off, the power supply is defective.
Does this module require external line fusing? Yes. To protect the field wiring and the facility’s electrical infrastructure, you must install an external slow-blow fuse or an appropriately sized circuit breaker on the AC line feeding the IC695PSA140 terminal block, as specified in the PACSystems hardware manual.
