The Omron C500-ID212, also known as 3G2A5-ID212, is a high-density DC input unit designed for efficient signal processing in industrial automation systems. Featuring 64 input points, it provides extensive input capacity for large-scale control applications while maintaining reliable performance. The module operates at 24 VDC (±10%/–15%) and consumes up to 300 mA of internal current at 5 VDC. It is built with a 2.2 kΩ input impedance and supports a 10 mA input current at 24 VDC, ensuring accurate signal detection. The input voltage thresholds are set at a minimum ON voltage of 10.2 VDC and a maximum OFF voltage of 3.0 VDC, providing stable and noise-resistant operation. It delivers rapid response with an input delay of 1.5 ms (max) and an output delay of 0.2 ms (max). The output section offers a 0.1 A switching capacity at 24 VDC (+10%/–15%), with a leakage current of 0.1 mA (max) and a residual voltage of 1.5 V (max). Weighing approximately 450 grams, the C500-ID212 features an A-shape form factor for practical installation within control panels. The C500-ID212 could be deployed in automation systems across North America, Europe, Asia, and other global regions, providing high-speed, stable, and accurate digital input performance for Omron’s C500 PLC platforms.
