The IC695PSD040 is a high-efficiency DC power supply module for the GE Fanuc PACSystems RX3i platform. It converts a 24 VDC input into precise internal voltage rails, supplying 5.1 VDC and 3.3 VDC to the RX3i backplane. Designed for industrial-grade reliability, the module ensures stable operation of CPUs, communication interfaces, and I/O components. Its dual-rail output and support for daisy-chaining make it suitable for scalable and redundant control system architectures.

What is the primary function of the IC695PSD040?
It converts 24 VDC field power into regulated 5.1 VDC and 3.3 VDC rails required by the RX3i backplane modules.
Can this power supply be used with Series 90-30 PLCs?
No; it is specifically designed for the RX3i Universal Backplane and is incompatible with Series 90-30 hardware.
Why would I daisy-chain two IC695PSD040 units?
Daisy-chaining increases power availability, supporting high I/O density systems and preventing voltage drops across the backplane, while also allowing for redundancy.
