Is the CP1W-8ER compatible with OMRON CP1E PLCs?

No. The CP1W expansion units are designed for the CP1L and CP1H series. The CP1E uses a different expansion connector and is not compatible with CP1W units.

How many CP1W-8ER units can I connect to a single CP1L PLC?

The maximum number of expansion units depends on the specific CP1L model. Refer to the OMRON CP1L hardware manual for the maximum expansion unit count and total I/O point limits.

What is the lead time for the CP1W-8ER?

Lead time varies by stock availability. Please submit an inquiry and our team will confirm current stock status and estimated delivery timeline within 1 business day.

Do you provide a warranty on OMRON CP1W-8ER units?

Yes. All units supplied by Konmask.com are covered by our quality assurance guarantee. Contact support@konmask.com for warranty terms.

Can I request a datasheet or technical documentation?

Yes. Contact us at support@konmask.com and our team will provide the relevant OMRON technical documentation for the CP1W-8ER.

Description

OMRON CP1W-8ER Relay Output Expansion Unit – CP1W Series

Imagine a production line where a critical relay output point fails mid-shift — conveyors halt, actuators freeze, and the entire downstream process grinds to a stop. Without a reliable expansion unit like the CP1W-8ER, engineers face unplanned downtime, costly emergency sourcing, and hours of rewiring. The OMRON CP1W-8ER Relay Output Expansion Unit is the precision component that keeps discrete control signals flowing, ensuring every output command from your CP1-series PLC reaches its destination without compromise.

Within the CP1W expansion family, the CP1W-8ER occupies a focused, high-reliability position: 8 relay output points in a compact DIN-rail form factor, purpose-built to extend the I/O capacity of OMRON CP1L and CP1H PLCs. As OMRON’s CP1 series has become one of the most widely deployed compact PLC platforms globally — trusted in packaging, food processing, material handling, and building automation — the CP1W-8ER serves as a foundational building block for scalable machine control architectures worldwide.
