Characteristic of digital inputs (see also Auto-Hotspot):
● Floating optocouplers with common reference potential (DIC)
● Switching range 14 ... 42 V (external control voltage)
● The digital inputs can be operated with a positive or negative voltage (reference potential
● With inverted switching logic, the logic function of the control input is active if no current is
● Maximum voltage: ±50 V
