OMRON C200H-OD211 Product Description

Overview

OMRON C200H-OD211 is a sinking NPN transistor output module for the OMRON SYSMAC C200H PLC series. It provides 12 discrete DC output channels to drive low-power 24 VDC field devices such as solenoid valves, indicators and solid-state relays. This legacy unit is end-of-life and widely stocked as MRO spare parts for retrofitting and maintaining existing C200H automation control systems.

Features

OMRON C200H-OD211 is designed as sinking type with 0.3 A rated current per channel at 24 VDC. It has a maximum ON response time of 0.2 ms and OFF response time of 0.3 ms, with residual voltage limited to 1.4 V maximum and leakage current below 0.1 mA. Each channel is equipped with an LED status indicator for quick on-site signal diagnosis. The module plugs directly into the C200H backplane and communicates output data with the CPU via the internal rack bus. It uses a removable screw terminal block for convenient wiring and replacement. Built-in channel overcurrent protection safeguards the PLC backplane against short-circuit damage. It complies with industrial EMC standards for noise immunity in factory environments.

Specs

Brand: OMRON Model: C200H-OD211 Product series: SYSMAC C200H Product category: Sinking transistor output module Output type: NPN sinking Channel count: 12 points Rated load: 24 VDC, 0.3 A per channel Response time: ON ≤0.2 ms, OFF ≤0.3 ms Residual voltage: 1.4 V max Leakage current: 0.1 mA max Termination: Removable screw terminal block Mounting: Backplane rack insertion Indicator: Individual channel LED Lifecycle: Discontinued

Principle

OMRON C200H-OD211 receives output bit commands from the C200H CPU through the rack backplane bus. When the corresponding output bit is enabled, the internal transistor turns on and sinks current from the 24 VDC load. When the output bit is cleared, the transistor switches off and de-energizes the load. The module monitors channel current continuously and triggers protection if overcurrent or short-circuit occurs.

Applications

OMRON C200H-OD211 is used for discrete DC load control in general industrial automation. Typical applications include packaging machinery, textile lines, printing equipment, conveyor systems, water treatment skids and legacy factory control cabinets. It serves as a replacement spare for failed C200H I/O systems.
