Product Overview
Downtime on a legacy control panel rarely waits for a purchase order. The IC200UDR040 is a GE VersaMax Micro 40-point PLC that keeps compact machines and remote skids running without a full control system rebuild. It packs 24 inputs and 16 relay outputs into one brick, so a single spare covers the whole I/O slice of a panel.
Emerson now owns the line, while the original design comes from GE Fanuc and GE Intelligent Platforms. That lineage matters when you are matching an existing VersaMax installation and need a drop-in unit rather than a redesign.

| Storage temperature | -40 to +85°C |
What the Key Ratings Mean on the Floor
The 24 VDC input bank suits standard field devices and panel sensors, while the 16 relay outputs at 2.0 A can switch small contactors, solenoids and indicator circuits directly. That reduces interposing relay count and simplifies troubleshooting.
Expansion to 170 I/O points lets you grow a skid without swapping the controller. For maintenance teams, this means one familiar platform across several machine sizes.
Where It Fits in Oil, Gas and Industrial Panels
On a wellhead or metering skid, the IC200UDR040 often handles valve status, level switches and pump commands. The relay outputs drive pilot devices, and the 24 VDC input scheme matches common instrument loops.
In a pipeline auxiliary panel, the same unit manages alarm inputs and fan or heater contactors. Because it runs from 24 VDC nominal, it fits DC-powered remote installations where AC supply is not practical.
For plant retrofit work, the VersaMax Micro form factor lets you replace a failed controller inside an existing enclosure. The 0 to +60°C ambient rating covers most sheltered cabinets, and the -40 to +85°C storage range survives unheated warehouses.
Integration and Programming Notes
The built-in RS-232 port supports direct programming and serial communication. An optional RS-485 interface is available, which helps when the controller must join a longer multi-drop network.
Both VersaPro and Proficy Machine Edition support this model, so existing project files remain usable. If you are wiring into a plant network, confirm cable and gateway requirements with your supplier before installation.
Service and Maintenance Perspective
From a maintenance engineer’s view, the value here is serviceability. Relay outputs are socket-friendly for field replacement, and the compact brick mounts inside standard enclosures without special hardware.
Inspect terminal torque and relay contact condition during scheduled shutdowns. Keep spare output relays and a known-good program copy on hand. Because the platform is widely deployed, technicians already familiar with VersaMax can commission a replacement quickly.
Official Emerson production status is unverified; the unit is currently available in aftermarket channels as of September 2026. Please verify current lifecycle status and availability with Oil AutoTech before ordering.
