AZURA® Detector DAD 6.1L, DAD 2.1L, MWD 2.1L Instructions, V6700
Connection Function
Autozero TTL Input
ƒ
Low active
Secure switching threshold at least 10 mA
A signal (short-circuit to ground) sets the measu-
ring signal to zero.
+5 V Provides a voltage of 5 V with respect to GND.
This makes it possible to supply a load that is
switched by an EVENT.
Protection: 5 V–50 mA
GND Reference point of the voltage at the signal
inputs.
+24 V Valve Event-controlled switching of 24 V
Protection against GND: 24 V–200 mA
Valve OUT Output is active until the valve condition has
been eliminated.
GND Reference point of the voltage at the signal
inputs.
