Omron CJ1W-DA021 Programmable Logic Controller

The Omron CJ1W-DA021 PLC Analog Output Unit provides 2 channels for generating voltage and current signals from a CJ-series Programmable Logic Controller system. Supported output ranges include 1 to 5 V, 0 to 10 V, ±10 V, 0 to 20 mA, and 4 to 20 mA with 1/6000 resolution, allowing PLC data to control compatible analog field equipment. The module operates at 24 VDC and extends the controller beyond digital switching by providing continuously variable electrical output signals for process-control applications. Its two-channel configuration suits systems requiring a compact amount of analog output expansion. The CJ1W-DA021 expands CJ1W analog control and belongs to the voltage and current PLC output range within Omron automation products.
