IC695PSA040 Functional Description   

The GE IC695PSA040 RX3i Universal Backplane Power Supply is a fundamental 40-watt power supply module within the PACSystems RX3i platform, designed to deliver reliable operational power for industrial automation control systems. This unit accepts a wide range of input voltages, operating effectively from 85 to 264 Volts AC or 100 to 300 Volts DC, making it versatile for various global power standards. Its primary function is to generate three critical output voltages: a +3.3 VDC for the internal logic of the CPU and other modules attached to the backplane, a +5.1 VDC output, and a +24 VDC relay output that can power external circuitry or field devices.

The design of the Power Supply IC695PSA040 General Electric emphasizes straightforward integration and operational safety. It is specifically engineered for compatibility with RX3i universal backplanes but requires exclusive use within its backplane segment; it cannot be mixed with other RX3i power supplies in the same chassis. For systems exceeding its 40-watt capacity, modules must be distributed across expansion backplanes, as this particular model does not support capacity expansion or redundancy configurations. This makes the GE Fanuc IC695PSA040 power supply an ideal choice for compact or dedicated control setups.

Operational status is clearly communicated through a set of four LED indicators for Power, P/S Fault, Over Temperature, and Overload, allowing for quick diagnostics. A physical ON/OFF switch, located behind a protective hinged door, enables technicians to disable the module safely. It is crucial to note that this switch controls the output power but does not isolate the incoming high-voltage supply, a safety feature highlighted by its designed tab to prevent accidental actuation.

In summary, the robust design and specific output capabilities of the IC695PSA040 Power Supply General Electric make it a cornerstone for ensuring stable and continuous operation in targeted PACSystems RX3i applications. By providing clean and regulated power to the critical system components, the IC695PSA040 GE Fanuc Universal Base Power Supply plays an indispensable role in maintaining the integrity and reliability of the entire automation control process.
