Specification

The OMRON CJ1W-ID261 and CJ1W-ID262 are high-density DC input units within the OMRON CJ1 PLC series, engineered for industrial automation environments requiring precise and rapid digital signal acquisition. These modules are designed to interface directly with 24 VDC sensors, switches, and other binary devices, converting external signals into logic-level inputs for the PLC processor. The ID261 variant provides 64 input points in a compact form factor, while the ID262 also delivers 64 points with slightly different electrical characteristics, both supporting sink (NPN) and source (PNP) wiring configurations. With response times optimized for high-speed applications, these units are ideal for assembly lines, packaging machinery, and process control systems. The modules feature robust isolation between the I/O and backplane, ensuring noise immunity and system reliability. Below is the detailed technical specification table for the CJ1W-ID261/ID262 series.

Input Wiring Compatibility: Both ID261 and ID262 support sink (NPN) and source (PNP) field devices, allowing flexible connection to a wide range of sensors and switches.
High-Speed Performance: With a response time of only 0.1 ms, these units are suitable for high-frequency counting and rapid event detection in fast-paced production lines.
Diagnostic Features: Each input channel has a green LED indicator, enabling immediate visual confirmation of signal status for efficient troubleshooting.
Robust Isolation: Photocoupler isolation between each input point and the backplane ensures electrical noise immunity and protects the PLC from voltage transients.
Compact Footprint: The 31 mm wide module saves valuable rack space in CJ1/CS1 backplanes, enabling high-density I/O configurations without expanding the system size.
Environmental Durability: Operates reliably in temperatures from 0 to 55°C and humidity up to 90% RH, making it suitable for factory floor conditions.
Easy Installation: Removable terminal blocks with M3 screw connections simplify wiring and allow quick module replacement without disturbing existing cabling.
