The Omron CJ1W-DA042V PLC Analog Output Unit provides 4 voltage output channels for generating control signals from a CJ-series Programmable Logic Controller system. It supports 1 to 5 V, 0 to 10 V, and ±10 V output ranges with 1/12000 resolution, allowing controller values to be converted into voltage signals for compatible industrial equipment. The four-channel configuration enables multiple external devices to receive independent analog voltage commands through one module. This expands the analog control capacity of the CJ1W architecture for machine and process applications requiring variable voltage outputs. The CJ1W-DA042V extends CJ1W analog control and forms part of the high-resolution PLC voltage output range available for Omron process automation.
