GE PACSystems RX3i IC695PSD040F – 24/48 VDC Power Supply for RX3i Racks (40 W Class)

The GE IC695PSD040F is a DC-input power supply designed for PACSystems RX3i baseplates. It’s the go-to choice when your panel already provides 24 VDC or 48 VDC, and you need a reliable 40 W-class supply to feed the RX3i backplane rails. From my experience, this model suits small to mid-sized RX3i configurations—CPUs, comm modules, and a moderate number of I/O—without pushing thermal limits. You might notice that it runs quietly and predictably, which tends to matter in applications like water treatment skids, packaging lines, and compact motion cells where downtime is just not acceptable.

Key Features

• 24/48 VDC Input – Accepts a nominal 24 VDC or 48 VDC supply, ideal for DC-powered panels.
• 40 W Class Output – Sized for typical RX3i CPU + comms + moderate I/O loads.
• Backplane Power Rails – Feeds the RX3i +3.3 V and +5 V rails used by CPUs and modules.
• Single-Slot Form Factor – Installs in the power-supply position of RX3i baseplates, saving cabinet space.
• Status Indication – Front-panel LEDs make it easy to verify input OK and supply health at a glance.
• Protection Features – Built for industrial use with overcurrent and fault protection on the backplane rails.
• RX3i Ecosystem Compatible – Typically works seamlessly with RX3i CPUs, comms, and discrete/analog I/O.

• IC695PSA040 – AC-input power supply (similar capacity) for panels with 120/240 VAC mains.
• IC695PSD140 – DC-input power supply with higher wattage for larger RX3i systems (check load profile).
• IC695CHS007 / IC695CHS012 / IC695CHS016 – RX3i baseplates (7/12/16‑slot) that accept this PSU.
• IC695CPU310 / IC695CPU315 / IC695CRU320 – RX3i CPUs/Controllers commonly paired with the IC695PSD040F.
• IC695CMM004 / IC695ETM001 – Communication modules used alongside this supply in networked systems.

One thing I appreciate is how predictable this unit is in brownout conditions—on a recent packaging retrofit, an IC695PSD040F held the rack stable during brief dips on a 24 VDC bus where a third-party supply had tripped. It’s not dramatic, but in many cases that’s what saves the shift.

Installation & Maintenance

• Panel & Ventilation – Mount the RX3i rack in a clean, dry enclosure with adequate airflow. Avoid heat sources; leave space above/below the rack for convection.
• Wiring – Use appropriately rated DC wiring from the 24/48 VDC source to the PSU input terminals. Tighten to spec and bond the rack ground to the panel ground bar.
• Load Planning – Sum module current consumption on the +3.3 V and +5 V rails and keep within the 40 W class capability; allow headroom for temperature.
• Safety – De-energize the panel before insertion or removal. Verify polarity on DC input. Use circuit protection upstream.
• Routine Care – Periodically inspect terminals for looseness, clear dust with dry air, and check front LEDs during PM rounds. Firmware is not applicable to this power-only module.

• Typically meets CE and UL for industrial control equipment; RoHS compliant in most cases.
• Manufactured under ISO 9001 quality systems by the GE/Emerson PACSystems line.
