Product details

What it is — CS1W-CT041 Counter Module

The Omron CS1W-CT041 is a counter module in the CS1W series, designed for high-speed counting on the CS Series backplane. It provides 4 digital inputs and 4 solid-state outputs in a single slot, connecting via a D-sub connector. Typical applications include position monitoring, batch counting, and pulse train measurement in automation cells.

4 digital inputs and 4 solid-state outputs: each input channel counts pulses at rates typical for encoder or proximity sensor signals; the solid-state outputs can drive small loads directly without an external relay. The CE, cULus, Lloyd, and NK approvals satisfy common global and marine compliance requirements.

Frequently asked questions

What is the closest alternative counter module if I need more I/O than the CT041?

The CS1W-HIO01-V1 is a higher-channel counter module in the same CS1W series with 12 digital inputs and 8 solid-state outputs, same backplane mount and D-sub termination. The CS1W-LC001 is a process control module and not a direct functional substitute for counting tasks.

What type of module is the CS1W-CT041?

It is a Counter Module with 4 digital inputs and 4 solid-state outputs.

What series does the CS1W-CT041 belong to?

It is part of the Omron CS1W series, designed for use with CS Series PLC backplanes.

Will the CT041 physically fit in a panel originally built for a CS1W-LC001?

Yes, both modules share the same backplane mounting and D-sub termination, so physical installation is compatible. However, the LC001 is a process control module with different functionality; the rack will need I/O mapping and programming adjustments to use the CT041 as a counter module.

What compliance certifications does the CS1W-CT041 carry?

It carries CE, cULus, Lloyd, and NK approvals. RoHS and REACH compliance is standard for Omron CS1W series modules, though not explicitly listed on this entry.
