CJ1W-DA08C 8-Channel Analog Output Unit 4-20mA 12-bit | Omron

The Original New Omron CJ1W-DA08C is an 8-channel analog output unit for SYSMAC CJ-series PLCs, designed to convert digital values from the CPU into precision analog current signals for industrial control applications. Each of the 8 outputs provides a 4–20 mA signal, making this unit ideal for controlling actuators, valves, drives, and process instrumentation in factory automation and process control systems. As a Special I/O Unit for CJ-series PLCs, it supports scaling functions and output hold capabilities for reliable analog control.

Core Engineering Highlights:
8 analog current outputs (4–20 mA) | 12-bit resolution | 4000 ms/unit conversion time  | 4–20 mA linear analog output type  | Scaling function supported  | Output hold function supported | 0°C to 55°C operating temperature | 90 × 31 × 89 mm | 140 g weight
