CJ1W-DA041 4-Channel Analog Output Unit ±10V/4-20mA | Omron

The Original New Omron CJ1W-DA041 is a 4-channel analog output unit for the SYSMAC CJ series programmable logic controller (PLC) platform, designed to convert digital data from the CPU into precise analog signals for control of field devices. It supports voltage (±10 V, 0–10 V, 0–5 V, 1–5 V) and current (4–20 mA) output signals, each channel independently configurable. Featuring 1/4000 resolution, 16-bit binary data conversion, and a 1.0 ms max/point D/A conversion period, this module delivers accurate and responsive analog control for variable speed drives, proportional valves, and actuators. Part of the CJ-series Special I/O Unit family, it is fully compatible with CJ1, CJ2, and NJ series CPU units. External 24 V DC power supply (200 mA) is required for operation.
