The Omron CJ1W-ID261 is a basic I/O digital input unit for Sysmac CJ-series PLCs, providing 64 DC input points in a single compact module to significantly expand input capacity without increasing panel space. It supports 24 VDC inputs with a permitted voltage range of 20.4 to 26.4 V and is compatible with both PNP and NPN transistor outputs, allowing connection of a wide variety of sensors, limit switches, push buttons, and other field devices.
Each input typically draws about 4.1 mA, ensuring reliable detection of ON/OFF states while maintaining low overall power consumption. The module offers configurable OFF/ON delay from 0 to 32 ms, which helps to filter out contact bounce and electrical noise in harsh industrial environments. With 64 inputs and 8 common terminals, the CJ1W-ID261 is ideal for large control systems such as machining lines, automated production lines, packaging equipment, and material handling systems that require many discrete input points.
The CJ1W-ID261 uses two Fujitsu-compatible FCN40 connectors (plugs not included) for I/O wiring, enabling high-density, multi-core cable connections and simplifying installation in large panels. It connects to the PLC via the CJ I/O Bus as a basic I/O unit and is fully compatible with CJ-series backplanes, allowing flexible system configuration and easy expansion. With its compact dimensions (31 × 90 × 66.5 mm) and light weight (around 100 g), the module fits neatly in crowded control cabinets. Overall, the CJ1W-ID261 is a cost-effective and space-saving solution for high-channel-count digital input applications in industrial automation.
