The circuit example is valid for all digital outputs!
The outputs are short circuit proof; a short circuit
generates an error.
The circuit example is valid for all digital inputs!
Signal level:
> 9.15V = "1" (38.2% of the control voltage applied)
< 8.05V = "0" (33.5% of the control voltage applied)
F1: Delayed action fuse
F2: Quick action electronic fuse; can be reset by switching the 24 VDC supply off and on again.

When the connection between transistor emitter of the initiator and X12/15
(GND24V of the Compax3 )is lost, it can not be guaranteed, that the Compax3
detects a logical „0".

The INSOR NPN types INHE5212 and INHE5213 manufactured by Schönbuch
Electronic do correspond to this specification.
