Plug connector X3 – digital inputs
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
either "-" or "+")
●
With inverted switching logic, the logic function of the control input is active if no current is
flowing through the control input
●
Maximum voltage: ±50 V
NOTICE
Observe maximum voltage!
Voltages greater than 50 V can destroy components, and safe isolation of the functional
voltages is no longer guaranteed!
