*1: If the power to models AAI141, AAI841, AAI135 and AAI835 is off or abnormal, the current input loop is in the
open state. Do not use current signals with other receiving devices. When in use, also use an external receiver
resistance in the voltage mode (Shunt resistant module part no. A1080RZ 250 ohm).
*2: Wiring resistance for A and C must be identical.
