Omron CJ1W-MAD42 CJ Series Mixed Analog I/O Unit 4AI 2AO

Omron CJ1W-MAD42 Mixed Analog I/O Module

The Omron CJ1W-MAD42 is a versatile mixed analog I/O module for CJ1 series programmable logic controllers, providing both analog input and output capability in a single module. This module features 4 analog input channels and 2 analog output channels, offering flexibility for applications requiring both measurement and control functions. The analog inputs support multiple signal types including 0-10VDC, 1-5VDC, 0-20mA, and 4-20mA, making it compatible with a wide range of industrial sensors and transducers. Each input channel provides 12-bit resolution for accurate measurement of process variables. The analog outputs provide 0-10VDC or 1-5VDC voltage signals for controlling external devices such as variable frequency drives, valve positioners, and analog indicators. The CJ1W-MAD42 connects directly to the CJ1 backplane, drawing operating power from the PLC power supply. LED status indicators provide at-a-glance monitoring of module activity. Easy configuration is achieved through CX-Programmer, allowing straightforward setup of input ranges, scaling, and output parameters. The module supports scalable data conversion, allowing input values to be scaled to engineering units for easy processing in the PLC. Applications include process control loops, temperature monitoring with transmitters, flow control, level measurement, and any application requiring both analog input measurement and output control.
