GE Fanuc IC200UDR120 VersaMax Micro PLC Controller

Overview

The IC200UDR120 VersaMax Micro PLC from GE Fanuc Emerson is a compact, self-contained programmable logic controller engineered for small and mid-scale control systems. By integrating the CPU, power supply, and discrete I/O into a single housing, this controller minimizes panel space while maintaining industrial reliability.

Designed for applications requiring relay outputs and flexible input logic, the IC200UDR120 supports deterministic control, high-speed counting, and serial communications, making it suitable for both machine-level automation and auxiliary process control.

Core Capabilities

The IC200UDR120 operates on a wide-range AC power supply and provides 20 onboard I/O points. It supports both positive and negative logic inputs, allowing direct connection to common 24 V DC field devices without additional signal conditioning.

Relay outputs enable direct switching of AC or DC loads, making this model particularly useful in mixed-voltage environments.

Comparison Within the VersaMax Micro Series

Compared with transistor-output VersaMax Micro models, the IC200UDR120 is better suited for applications requiring direct load switching or higher voltage compatibility. Systems needing fast DC switching or silent operation may prefer transistor-based variants, while relay-based designs excel in versatility and electrical isolation.

Frequently Asked Questions

Can the IC200UDR120 be expanded with additional I/O?

Yes. The controller supports VersaMax Micro expansion modules, allowing the system to scale beyond the onboard I/O.

Does this model include analog inputs or outputs?

No analog channels are integrated. Analog functionality can be added through compatible expansion modules.

Is the relay output suitable for AC loads?

Yes. Each relay output supports up to 250 V AC, making it suitable for direct control of contactors, solenoids, and other AC devices.
