OMRON MODULE C200H-OC225 C2OOH-OC225 C200HOC225

Omron C200H-OC225 Relay Output Module

Overview

The C200H-OC225 is a 16-point relay output module for the Omron C200H PLC family.

Available C200H documentation describes it as a relay output unit rated for 250 VAC / 24 VDC, with 2 A per point and 8 A per unit capacity for resistive loads.

The same C200H material places it among the standard discrete output modules used in the C200H rack-based control platform.

What makes this module practically useful is its straightforward relay-based output design. In real panels, that usually means better flexibility when the machine needs to switch mixed field loads instead of relying only on transistor-output logic.

For legacy Omron systems, a module like this is often valued because it preserves the original rack layout, terminal structure, and output behavior without forcing the user into a broader control-platform change.

This is an engineering inference based on the module’s published relay-output role and C200H installed-base context.

Technical Data

Application Value

The C200H-OC225 fits well in legacy machine controls, process skids, utility panels, conveyor systems, and general automation cabinets that already use the C200H architecture.

Because it offers 16 relay outputs, it is especially practical where a controller must switch several contact-style field devices from one module without moving to separate relay interface hardware for every channel.

This application view follows from the module’s published point count and relay-output format.

It also has strong replacement value. In older PLC systems, exact rack-module continuity often matters more than adding new features.

Keeping the same 16-point relay card usually helps preserve field wiring, cabinet labeling, and machine-side maintenance logic, which can reduce downtime during service work. This is an engineering inference based on the C200H rack-module family structure and the module’s specific relay-output identity.

Replacement and Selection Perspective

For replacement projects, the C200H-OC225 should be selected as a system-matched relay output card, not just by the fact that it has 16 points.

Buyers should verify the installed module code, switching voltage and current needs, rack compatibility, and whether the machine depends on relay-output behavior rather than transistor or triac outputs. 

On older PLC systems, those distinctions usually matter more than outward similarity.

This recommendation is grounded in the module’s published relay class, point count, and load ratings.

FAQ

Q1: What kind of module is C200H-OC225?
It is a 16-point relay output module for the Omron C200H PLC platform.

In practical terms, it expands a C200H rack with field-switching outputs rather than logic inputs or analog channels.

Q2: Why do relay outputs still matter on older PLC systems?
Relay outputs remain useful because they are electrically flexible and can switch a wide variety of field loads.

In legacy machines, they are often part of the original design philosophy, so keeping the same relay module helps preserve the intended output behavior and wiring approach. 

This is an engineering inference based on the module’s published relay-output characteristics.

Q3: What applications fit this module best?
It fits legacy industrial control panels, machine automation cabinets, conveyors, and utility control systems where a C200H PLC still manages discrete outputs.

The 16-point format makes it especially practical when several output channels need to stay grouped in one rack slot.

This is an engineering inference based on the module’s published point count and C200H system role.

Q4: Why is the 8 A per unit figure important?
Because it defines the practical loading limit of the whole module, not just a single output.

Even when each point can switch up to 2 A, the overall unit total still matters for reliable operation and long-term relay life. 

This is an engineering inference based on the module’s published per-point and per-unit ratings.

Q5: What should be checked before ordering?
Check the installed part number, rack family, output type, switching voltage, and actual field load per point and per unit.

Those checks usually prevent the most common replacement mistakes on older relay output cards.
