Product Overview

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.

FAQ for CJ1W-MAD42

What's the advantage of mixed analog I/O unit?
MAD42: 4 inputs + 2 outputs in single unit. Cost-effective when you need both analog input and output. Saves expansion slots vs separate input and output units.
Can I configure each channel independently?
Yes, each input and output channel independently configurable for voltage or current. Set via DIP switches and software configuration.
What's a typical application?
Process control: read pressure/flow (analog input), control valve/VFD (analog output). Temperature control: read temperature (input), control heater (output). Closed-loop control in one unit.
Do I need to configure this unit?
Yes, analog units require configuration in CX-Programmer: set input/output type per channel, scaling, alarm limits. Configuration downloads to CPU.
