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.
Key ratings and what they mean
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. Operating temperature range 0°C to 55°C covers most cabinet environments without active cooling. The CE, cULus, Lloyd, and NK approvals satisfy common global and marine compliance requirements.
