Input Circuits
The following diagrams show the internal circuit of the analog input section.
CJ1W-AD041-V1/AD081-V1 CJ1W-AD042
Terminal Arrangement
The signal names corresponding to the connecting terminals are as shown in the following diagram.
CJ1W-AD041-V1 CJ1W-AD081-V1
CJ1W-AD042
Note: 1. Set the analog input number that you use and input signal range for each analog input, using the memory area or support software. The
input signal range can be set separately for each input number.
2. The AG terminals are connected to the 0 V analog circuit in the Unit. Connecting shielded input lines can improve noise resistance.
3. Do not connect anything to NC terminals.
4. To use a current input with the CJ1W-AD042, connect the positive current input terminal and positive voltage input terminal with the
enclosed short bar.
5. Connect a surge suppressor to inductive loads in the system (e.g., magnetic contactors, relays, and solenoids).
