Product Overview

The OMRON C200H-OC222 is a high-reliability relay output unit designed for the C200H series programmable logic controller (PLC) system. As a contact output unit, this module provides 12 isolated relay outputs capable of switching both AC and DC loads, making it an essential component for industrial automation systems requiring robust contact switching capabilities. The C200H-OC222 mounts directly to the C200H backplane and is fully compatible with C200H, C200HS, and CS1 series PLC systems, offering flexibility for both new installations and legacy system expansions.

Each of the 12 output points is equipped with a replaceable relay contact rated at 2A at 250 VAC or 24 VDC for resistive loads, providing sufficient switching capacity for solenoid valves, contactors, indicator lamps, and other industrial control devices. The module features a common terminal configuration, with outputs arranged in groups for simplified wiring and organized panel layouts.

Technical Specifications

Key Features

• 12 isolated relay outputs provide high-density contact switching in a compact module footprint.

• LED indicators per point provide immediate visual confirmation of output status for rapid troubleshooting.

• Removable terminal block facilitates field wiring and module replacement without rewiring.

• Photo-coupler isolation ensures reliable operation in electrically noisy industrial environments.

• Compatible with C200H, C200HS, and CS1 series PLC systems for flexible system integration.

• Backplane mounting simplifies installation and eliminates external wiring between modules.

Applications

The OMRON C200H-OC222 relay output unit is deployed across a wide range of industrial automation sectors requiring reliable contact switching. In manufacturing environments, the module controls solenoid valves for pneumatic actuators, contactors for motor starters, and indicator lamps on operator panels. In packaging machinery, the outputs drive clutch and brake mechanisms, heat-seal elements, and product diversion gates.

Additional applications include material handling systems where the module controls conveyor direction and stopping, and process automation where it actuates pump starters, valve positioners, and alarm annunciators. The module's compatibility with C200H series racks makes it suitable for both new machine builds and retrofit projects where existing C200H-based control systems require I/O expansion or replacement.
