Terminal Arrangement
The signal names corresponding to the connecting terminals are as shown in the following diagram.
CJ1W-MAD42
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 terminal (A7, B7) is connected to the 0 V analog circuit in the Unit. Connecting shielded input lines can improve noise resistance.
3. The N.C. terminals (A4, B4) are not connected to internal circuit.
