Still keeping legacy control panels alive with hard-to-find PLCs?
The IC200UDR002 from GE is the practical answer. This VersaMax Micro 14-point PLC packs 8x 24 VDC inputs and 6x relay outputs into a compact controller that keeps small machines, skids and utility panels running. Emerson now owns the line, but the installed base across oil, gas and industrial automation remains huge. That is why ready-to-ship spares matter.
What Is the IC200UDR002?
The IC200UDR002 is a VersaMax Micro PLC originally built by GE Fanuc / GE Intelligent Platforms. It handles 14 I/O points: eight 24 VDC inputs and six relay outputs. A single RS-232 serial port covers programming and simple peer connections. The unit runs on 24 VDC nominal input power, so it drops straight into DC control cabinets common in remote and field installations.

Why the I/O Mix Matters
The eight 24 VDC inputs suit standard field devices such as proximity switches, pressure switches and pushbuttons. The six relay outputs switch loads directly, which simplifies panels that drive solenoids, small contactors or indicator lamps. Fourteen points is a sweet spot for standalone equipment that does not justify a larger rack.
Serial Communication and Programming
The RS-232 port supports VersaPro and Proficy Machine Edition. That means your existing project files stay usable. If you are replacing a failed unit, you can reload the original logic rather than rewrite it.
Where It Fits in the Field
Wellhead and Pump Control
Remote wellhead panels often run on 24 VDC and need a handful of digital points. The IC200UDR002 fits this profile, and its 0 to +60°C operating range covers most sheltered field enclosures.
Small Skids and Package Units
Metering skids, chemical injection packages and small compressor units frequently use compact PLCs for start/stop, alarm and valve logic. The relay outputs handle pilot devices without extra interposing relays.
Utility and Test Benches
Workshops and test benches value the simple serial programming path. Technicians can connect a laptop, load logic and verify I/O quickly.
Replacement and Upgrade Guidance
This is the practical angle for most buyers. When a VersaMax Micro fails, downtime costs more than the part. The IC200UDR002 remains available through aftermarket channels, though official Emerson production status is unverified. Before ordering, confirm your existing model, I/O count and power arrangement match this unit. Keep your Proficy Machine Edition project backed up so commissioning is fast.
Integration Notes
The built-in RS-232 port is a serial interface. Wiring into plant networks may require an external gateway or connection module. Confirm cables and any gateway requirements with your supplier before installation.
Maintenance and Reliability
Inspect the controller periodically for loose terminals, dust buildup and enclosure temperature. Relay outputs are electromechanical, so high-cycle loads deserve attention during routine checks. Keep spare units on the shelf to avoid extended downtime.
