IC695PSD140 Power Supply: Reliable Redundancy for RX3i Systems

Why the IC695PSD140 Matters for Modern Control Systems

In today's industrial automation landscape, maintaining uptime is critical. Power supply failures can halt production lines and lead to costly downtime. The GE IC695PSD140 power supply module addresses this challenge by supporting redundancy and load sharing, ensuring continuous operation in demanding environments.

As part of the PACSystems RX3i family, this module delivers reliable DC power for CPUs and I/O modules. Engineers seeking a robust power solution for their RX3i backplane will find the IC695PSD140 a versatile choice.

Introducing the IC695PSD140 Power Supply Module

The IC695PSD140 is a multipurpose power supply module manufactured by Emerson Automation, formerly GE Intelligent Platforms. It is designed for the PACSystems RX3i platform and occupies two slots in the universal backplane.

This module accepts an input voltage range of 18 to 30 VDC and provides three outputs: 5.1 VDC, 3.3 VDC, and 24 VDC. With a maximum output power of 40 Watts, it can power multiple RX3i modules efficiently.

Technical Specifications and Performance

The IC695PSD140 offers a nominal output current of 0 to 6 Amps at 5.1 VDC and 0 to 9 Amps at 3.3 VDC. The 24 VDC output delivers 0 to 1.6 Amps for power circuits and output relay modules.

Maximum input power is 60 Watts at full load, and the module supports up to four daisy-chained units in a single backplane. Output ripple and noise are both rated at 150 mV, ensuring clean power delivery.

Four LED indicators provide status for power, P/S fault, overtemperature, and overload conditions. The module includes an on/off switch on the front panel for convenient control.

Applications in Redundant and Load-Sharing Configurations

The IC695PSD140 is ideal for applications requiring high availability. In a typical packaging line, two power supplies can be configured in redundant mode to ensure uninterrupted operation if one unit fails.

For increased capacity, up to four modules can share the load across the RX3i backplane. This flexibility makes the IC695PSD140 suitable for both critical infrastructure and expandable systems.

Real-World Application Example

Consider a water treatment plant using a PACSystems RX3i controller. By deploying two IC695PSD140 modules in a load-sharing configuration, the plant maintains power integrity even during maintenance or unexpected outages, minimizing process interruptions.

Compatibility and Integration

The IC695PSD140 is compatible with any RX3i CPU and installs directly into the universal backplane. It supports redundancy and increased capacity modes, but users must avoid mixing it with IC695PSD040 or IC695PSA040 modules in these configurations.

Terminal connections accept wire sizes from #14 to 22 AWG, with a maximum terminal current of 6 Amps. The module does not provide isolation, so proper grounding is essential.
