GE IC695PSD040F Replacement for PACSystems RX3i Series

Product Overview

GE IC695PSD040F Replacement for PACSystems RX3i Series: Smooth Migration from Legacy DC Power Infrastructure

The GE IC695PSD040F is a 40-Watt DC input power supply module designed for the GE PACSystems RX3i control platform. As legacy GE Series 90-30 and early RX3i installations approach end-of-service milestones, plant engineers and automation integrators increasingly rely on the IC695PSD040F as a direct, wiring-compatible replacement that preserves existing rack architecture, minimizes re-engineering effort, and dramatically reduces planned or unplanned downtime.

This module accepts a 24 VDC nominal input and delivers regulated backplane power to the IC695CHS012 or IC695CHS016 universal backplane chassis, supporting mixed CPU, I/O, and communications module populations without requiring backplane redesign. Its compact form factor fits the standard RX3i slot pitch, making it a true drop-in upgrade from earlier IC695PSD010 AC-input power supplies in sites that have already converted their panel power distribution to 24 VDC bus architecture.

Seamless Upgrade Solutions

A successful IC695PSD040F migration rarely involves the power supply in isolation. In most RX3i retrofit projects, the power supply replacement is coordinated alongside a broader system refresh. When the existing IC695CPE302 or IC695CPE305 CPU module is also approaching obsolescence, engineers often upgrade to the IC695CPE400 high-performance CPU simultaneously, taking advantage of the shared backplane to avoid a second maintenance window. The IC695CHS016 16-slot universal backplane chassis provides the physical foundation for both the new power supply and any expanded I/O population, and its backward compatibility with existing RX3i modules means previously installed IC694MDL754 discrete output modules and IC695ALG600 analog input modules can remain in service.

On the communications side, sites running PROFIBUS DP networks will retain their IC695PBM300 PROFIBUS master module, which continues to operate normally on the refreshed backplane. Ethernet-connected systems using the IC695ETM001 Ethernet module similarly require no reconfiguration after the power supply swap, as the module draws its operating power from the backplane rather than a dedicated supply. For installations that include remote I/O drops connected via RX3i expansion racks, the IC695LRE001 local rack expansion module maintains its link to the primary rack without interruption during the power supply replacement procedure.

Panel integrators working on control cabinet retrofits should also account for the 24 VDC panel bus infrastructure feeding the IC695PSD040F. In many legacy installations, the upstream 24 VDC power distribution relies on aging DIN-rail mounted DC/DC converters or rectifiers that may themselves be candidates for replacement. Ensuring the upstream supply can deliver the full 40 W load with adequate voltage regulation is a prerequisite for stable RX3i operation. Signal isolators and terminal blocks within the same cabinet should be inspected for compatibility with the updated wiring layout during the same maintenance window to minimize future interventions.

Retrofit Guidance FAQ

Q: Can I replace the IC695PSD040F without removing the CPU or I/O modules from the backplane?
A: Yes. The IC695PSD040F is designed for field replacement. Isolate the 24 VDC input at the panel disconnect, remove the module by releasing the locking tabs, and insert the replacement unit. The CPU and I/O modules remain seated in the backplane. Restore power and verify the POWER LED illuminates solid green before resuming operations.

Q: Will my existing ladder logic or Structured Text programs require modification after the power supply replacement?
A: No. The IC695PSD040F is a passive power infrastructure component. It has no firmware, no configuration parameters, and no interaction with the PACSystems Machine Edition programming environment. Your IC695CPE302 or IC695CPE400 CPU retains its program in battery-backed SRAM or flash memory throughout the replacement procedure.

Q: Is the IC695PSD040F compatible with both IC695CHS012 and IC695CHS016 backplanes?
A: Yes. The module is compatible with all standard RX3i universal backplane chassis variants. It occupies the dedicated power supply slot at the left end of the chassis and does not consume a general-purpose I/O slot.

Q: What communications protocols are unaffected by the power supply replacement?
A: All protocols operating through backplane-powered modules are unaffected, including PROFIBUS DP (IC695PBM300), Ethernet/IP and Modbus TCP (IC695ETM001), and serial communications through IC695CMM002 serial modules. Protocol configuration stored in the CPU is preserved throughout the replacement.

Q: How much physical space does the IC695PSD040F require in the control cabinet?
A: The module occupies a single RX3i slot position within the backplane chassis. No additional DIN-rail space is required. The external wiring connection is a standard 24 VDC two-wire terminal block, identical to the predecessor IC695PSD040 revision, so existing cable lengths and routing are preserved.

Q: Can this module replace an IC695PSD010 AC-input power supply?
A: The IC695PSD040F requires a 24 VDC input and cannot accept 120/240 VAC directly. Sites migrating from IC695PSD010 AC-input supplies must first install an appropriate AC-to-DC converter in the panel to provide the 24 VDC bus. This is a common upgrade path for facilities standardizing on 24 VDC panel architecture.
