CJ1W-ID261 Key Advantages
PNP/NPN Polarity Universal for Strong Compatibility: The CJ1W-ID261 allows free selection between NPN and PNP output polarities. Whether field sensors are NPN or PNP type, they can be directly connected without additional conversion circuits, significantly reducing selection complexity and wiring effort.
64-Point High-Density Input Saves Cabinet Space: The CJ1W-ID261 integrates 64 input points in a compact 31mm-wide module, replacing multiple low-point-count modules. Significantly reduces I/O module count and control cabinet footprint compared to 16-point or 32-point modules.
Adjustable Digital Filter Adapts to Different Environments: The CJ1W-ID261 allows filter time to be flexibly configured from 0ms to 32ms to suit different industrial environments. For switch contact bounce, larger filter values prevent false triggering; for high-speed signals, 0ms filter provides the fastest response.
15µs High-Speed Response for Demanding Applications: The CJ1W-ID261 features an ON response time as low as 15µs and an OFF response time as low as 90µs. Suitable for high-speed counting, rotary encoder signal acquisition, and short-duration pulse detection where timing precision is critical.
FCN40 Standard Connector for Flexible Wiring: The CJ1W-ID261 uses industry-standard FCN40-type 40-pin rectangular connectors, supporting flexible wiring via Omron XW2B terminal blocks or dedicated cables. Accommodates both high-density集中 wiring and distributed wiring via terminal blocks.
