• OMRON Type Designation: CJ1W

• Description: OUTPUT MODULE 2 ANALOG

Features

Analog Input Units
• Input up to eight analog signals with one Unit.
• Functions include line disconnection detection, averaging, peak value holding, offset/gain adjustment, and scaling. (Offset/gain adjustment is not supported by the CJ1W-AD042. Scaling is supported only by the CJ1W-AD042.)
• High-speed A/D conversion in 20 μs/point with direct conversion function * (CJ1W-AD042 only).
Analog Output Units
• Output up to eight analog signals with one Unit.
• Functions include output holding, offset/gain adjustment, and scaling. (Offset/gain adjustment is not supported by the CJ1W-DA042V. Scaling
is supported only by the CJ1W-DA08V/DA08C/DA042V.)
• High-speed D/A conversion in 20 μs/point with direct conversion function * (CJ1W-DA042V only).
Analog I/O Units
• Input up to four analog signals and output up to two analog signals with one Unit.
• Functions include line disconnection detection, input averaging, scaling, input peak value holding, output holding, ratio conversion, and offset/
gain adjustment.
* Direct Conversion Instructions for High-speed type can be used to create a consistent response time from input through data processing and
output. With the Machine Automation Controller NJ-series, the direct conversion function cannot be used. This function is supported only by the
CJ-series CPU Unit.
