2. The input signal ranges for each input are set in the Data Memory (DM). They can be set in units of input numbers.
3. The AG terminals are connected to the 0 V analog circuit in the Unit. Connecting shielded input lines can improve noise resistance.
4. Do not connect anything to NC terminals.
5. To use a current input with the CJ1W-AD042, connect the positive current input terminal and positive voltage input terminal with the
6. Connect a surge suppressor to inductive loads in the system (e.g., magnetic contactors, relays, and solenoids).
