Input circuits
All inputs (apart from the "Analog In" input) are electrically isolated by optocouplers
from the voltage supply of the PD4-N and designed for 5-24 V input signals at an input
current of 8 mA.
Note:
The voltage must not exceed 24 V. It should drop below 2 V for safe switching off and
be at least 4.5 V for safe switching on.
