CJ1W-DA021 2-Channel Analog Output Unit ±10V/4-20mA | Omron

The Original New Omron CJ1W-DA021 is a 2-channel analog output unit for SYSMAC CJ-series PLCs, designed to convert digital values from the CPU into precision analog voltage or current signals for industrial control applications. Each of the 2 outputs is independently configurable for voltage ranges including –10 to +10V, 0 to 10V, 0 to 5V, 1 to 5V, or 4 to 20 mA current output. With 12-bit resolution and photocoupler isolation between outputs and PLC signals, this Special I/O Unit delivers reliable analog control for actuators, drives, valves, and other field devices.

Core Engineering Highlights:
2 analog outputs (voltage/current configurable) | 12-bit resolution (1/4000 full scale) | Output ranges: –10 to +10V, 0–10V, 0–5V, 1–5V, 4–20mA | 1 ms per point D/A conversion | 0.5 Ω output impedance (voltage) | 0.3% voltage / 0.5% current accuracy | Removable screw terminal block | 90 × 31 × 89 mm | 150 g weight | 0°C to 55°C operating temperature
