Instruction manual
Optocoupled input contacts’ electrical features:
-
Opto coupler IN 1: Pin 5 and 6.
-
Opto coupler IN 2: Pin 2 and 4.
-
Opto coupler IN 3: Pin 3 and 4.
-
Inputs can be driven with any polarity with respect to their own earth return and they work with alternate
or direct current.
-
Correct operation is guaranteed if input voltages comply with the following requirements:
Input DC [V]
Input AC [V rms]
