CJ1W-ID212 16-Point High-Speed DC Input Unit 24V Screw Terminal | Omron

The Original New Omron CJ1W-ID212 is a 16-point high-speed DC input unit for SYSMAC CJ-series PLCs, designed for applications requiring rapid signal acquisition. It accepts 24V DC sink/source inputs with a configurable input response time (0–32 ms) that can be set to deliver an ultra-fast ON response of 15 μs. This makes it ideal for high-speed counting, positioning feedback, and time-critical event detection. The 18‑point removable screw terminal block provides secure wiring and simplified maintenance. PNP/NPN polarity compatibility allows connection to a wide range of field devices.

Core Engineering Highlights:
16 high-speed digital inputs | 24V DC (20.4–26.4V range) | 7 mA typical input current | 15 μs ON / 90 μs OFF response time (at 0 ms filter setting)| 3.3 kΩ input impedance| 16 points, 1 common| 130 mA current consumption| Removable 18‑point screw terminal block| 90 × 31 × 89 mm | 110 g max
