Consistent Microsecond Throughput:

Models with Direct Conversion Join

the Lineup

• Analog Input Units for converting analog input signals into

binary data

• Analog Output Units for converting binary data into analog

output signals

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.

CJ1W-AD/DA/MAD *5 The D/A conversion period is the time required for the Analog Output Unit to convert and output the data that was received from the CPU Unit. It takes at least one cycle for the data stored in the CPU Unit to be read by the Analog Output Unit. (The direct conversion function of the CJ1WDA042V can be used to output data immediately from the CPU Unit.
