Available for worldwide express delivery with a 12-month warranty.
What Is the IC695PSD140?
The IC695PSD140 is a Multi-Purpose 40-Watt DC power supply module for the GE Fanuc PACSystems RX3i platform. Unlike the standard IC695PSD040, the IC695PSD140 is engineered for advanced power architectures — it supports both load-sharing and Hot Standby controller redundancy configurations, making it the correct choice for any RX3i system where continuous availability is required. Up to four IC695PSD140 (or IC695PSA140) multipurpose power supplies can be installed in a single RX3i universal backplane simultaneously. Developed under GE Fanuc Intelligent Platforms and now maintained by Emerson Automation, the IC695PSD140 is installed in critical industrial applications across oil and gas, power generation, water utilities, and continuous process manufacturing globally.

Redundancy and Load-Sharing Architecture
The critical differentiator of the IC695PSD140 over the IC695PSD040 is its multipurpose capability. In load-sharing mode, multiple IC695PSD140 units share the backplane current demand proportionally, increasing total available output power and providing hardware-level redundancy: if one supply fails, the remaining units continue to power the rack without interruption. This is essential for applications with RX3i Hot Standby redundancy CPUs (IC695CRU320) where loss of backplane power would trigger an unplanned system failover. When combining with AC input power supplies, the IC695PSD140 can coexist in the same backplane with IC695PSA140 units, allowing mixed AC/DC input redundancy architectures. Note: The IC695PSD140 is not backward-compatible with non-multipurpose supplies for shared operation — do not mix IC695PSD140 with IC695PSD040 in the same backplane for shared operation.
Installation Advice
Before installing the IC695PSD140 in a load-sharing configuration, verify that the On/Off switch on the front panel is accessible and clearly labelled for operators. In load-sharing mode, switching off one supply will redistribute its load to the remaining units — a sudden switch-off under full load can momentarily stress the remaining supplies. Always confirm that the combined power demand of all installed modules does not exceed the aggregate output capacity of the multipurpose supply configuration. When powering up for the first time after installation, observe all four LEDs simultaneously: the Power LED should turn green within one logic scan of the CPU initializing. An amber Power LED after power application indicates the output switch is in the off position. Wiring terminals accept 14 to 22 AWG wire — use industrial-grade, screened cable for the 24 VDC input in environments with high EMI.
Frequently Asked Questions
Q: What is the difference between the IC695PSD140 and the IC695PSD040?
A: The IC695PSD140 is a multipurpose supply that supports load sharing and controller redundancy — up to four units can be combined in one backplane. The IC695PSD040 is a standard supply limited to one unit per backplane with no redundancy capability.
Q: Can I mix IC695PSD140 and IC695PSA140 in the same backplane?
A: Yes. Both are multipurpose supplies and can coexist in the same RX3i universal backplane, enabling mixed AC and DC input redundancy architectures — a common requirement in industrial plants with both AC mains and DC battery-backed power available.
Q: Does the IC695PSD140 require any jumper or DIP switch configuration?
A: No. The IC695PSD140 has no hardware configuration switches. Its operating mode (standalone, load sharing, or redundancy) is determined entirely by the system configuration performed in Proficy Machine Edition software.
