CJ1W-DA021

The Omron CJ1W-DA021 output module is an analog output module. It is part of the Omron CJ series, and it is a CJ-series special I/O unit. This unit features 2 analog outputs that support a variety of output signal ranges. This signal ranges include ranges from -10 to 10 Volts, 0 to 10 Volts, 0 to 5 Volts, 1 to 5 Volts, and 4 to 20 milliamps. It supports photocoupler isolation between the outputs and the PLC signals, but it does not support isolation between the outputs. The CJ1W-DA021 output module’s maximum impedance rating is 0.5 ohms maximum with voltage output. Its full-scale resolution rating is 4,000, and its D/A conversion period is 1 ms/point. The CJ1W-DA021 module supports accurate and precise analog output signals for various applications. The unit supports a voltage accuracy rating of +/-0.3% of full scale and a current accuracy rating of +/-0.5% of full scale at 23 degrees Celsius, +/-2 degrees Celsius. To ensure reliable operation, the CJ1W-DA021 requires an external power supply rated at 24 Volts DC (+10%, -15%). It operates with a maximum external power supply current rating of 140 mA. The current consumption rating of the CJ1W-DA021 output module is 120 mA at 5 Volts DC. It supports 12-bit resolution for the analog outputs and a removable terminal block for easy external connections. The CJ1W-DA021 module is designed to be compact and efficient. Its dimensions are 31 × 90 × 65 mm (W × H × D), and it weighs 150 g maximum.
