GE IC695PSD140 Multipurpose Power Supply Overview
The GE IC695PSD140 is a PACSystems RX3i power supply module manufactured by Emerson Automation, originally by GE Intelligent Platforms. As a multipurpose unit, it supports both load sharing and redundancy applications, making it a versatile choice for critical industrial systems. This review covers its technical specifications, practical features, and value based solely on provided data.
Key Specifications and Outputs
The IC695PSD140 accepts an input voltage range of 18 to 30 VDC and delivers multiple regulated outputs. It provides 0 to 6 A at 5.1 VDC, 0 to 9 A at 3.3 VDC, and 0 to 1.6 A at 24 VDC for relay circuits. Total output power is 40 watts maximum, with individual limits of 30 watts for 5.1 V and 3.3 V outputs. Ripple and noise are both rated at 150 mV, ensuring stable power for connected modules.
Redundancy and Load Sharing Capabilities
Users can install up to four IC695PSD140 modules in a single RX3i universal backplane for increased capacity or redundant operation. In load sharing mode, all units must connect to the same power source, and the front-panel on/off switch should remain on to maintain system integrity. Note that this module is incompatible with IC695PSD040 or IC695PSA040 in redundant or increased capacity modes, as mixing models may cause damage.
LED Indicators and Diagnostics
Four LEDs on the front panel provide real-time status: Power (green/amber), P/S Fault (red), Overtemperature (amber), and Overload (red). These indicators help technicians quickly identify operational issues, such as overheating or excessive load, without additional tools.
Installation and Compatibility
The module occupies two slots in the RX3i universal backplane and requires #14–22 AWG wire for connections, with a maximum terminal current of 6 A per input. It provides no isolation between outputs. This power supply works with any RX3i CPU and can serve as the sole unit or part of a multi-module configuration, offering flexibility for system designers.
Conclusion
The GE IC695PSD140 delivers reliable, regulated power with redundancy support for PACSystems RX3i applications. Its multiple outputs, LED diagnostics, and load sharing abilities make it a practical choice for engineers seeking robust power management. Always verify compatibility with other power supply models to ensure safe operation.
