Open collector outputs
The ASD criteria “Alarm I”, “Alarm II” and “Fault” (all fault
events) are available as open collector outputs.
Parallel and feedback indicators and other consumers
(e.g. relays) can be connected to the open collector outputs.
In ASD 535-1 and -3 the output on terminal 8 is not “Alarm II”
but rather freely programmable (it is always identical with the
programming on relay 3 of the AMB 35).

Notices
•
When connecting inductive consumers (e.g. relays), a freewheel diode is to be installed directly at the con-
•
The outputs are 0-Volt switched and have a loading capacity of max.
100 mA
per output. All outputs together
cannot switch more than
200 mA
. The electrical strength is 30 VDC per output. The outputs are not short-
circuit-proof and not potential-free. Connection to the outputs affects the overall power consumption of the
ASD 535.
