Description

Overview

The IC200UDR040 from GE Fanuc is a compact 40-point programmable logic controller designed for discrete machine control applications requiring a mix of high-density digital inputs and electromechanical relay outputs.

This unit integrates input processing, relay switching, high-speed counting capability, and onboard power distribution into a single controller body, making it suitable for standalone machine-level automation without external expansion hardware.

System Configuration

• Total I/O capacity: 40 points

• Digital inputs: 24 × 24 VDC configurable logic inputs

• Digital outputs: 16 × relay (Form A / SPST, normally open)

The controller supports mixed logic input configurations (sink/source wiring), enabling flexible field device integration.

A subset of inputs is dedicated to high-speed event capture for counting applications.

FAQ

Can relay outputs support PWM or fast switching?
No. The outputs are mechanical relays and are intended for low-frequency switching only.

Does this PLC support high-speed counting?
Yes. It supports up to four high-speed counter configurations with 16-bit or 32-bit resolution.

Is external power required for outputs?
Yes. Relay outputs require an external AC or DC load supply.
