Product questions
How many analog channels does the CJ1W-MAD42 have and what signals does it support?
The unit has four analog inputs and two analog outputs. Both support -10 to 10 V, 0 to 5 V, 0 to 10 V, 1 to 5 V, and 4 to 20 mA signal ranges.
What resolution and terminal connection does the CJ1W-MAD42 offer?
Omron lists a resolution of 1:4000, scalable to ±32000, or 1:8000. The CJ1W-MAD42 uses a screw-terminal connection.
What should be checked if a CJ1W-MAD42 analog output does not respond?
An actual user discussion identifies output enable, I/O configuration, scaling and wiring as possible checks, but does not establish a universal cause. Have a qualified controls technician consult the applicable Omron manual and verify the configuration before changing a running system.
