Connection of BX-AIM advanced input module

The BX-AIM advanced input module can be used as monitored input for polling potential-free contacts or as detection zone
for connecting collective detectors. Among other things, it can be used to connect intrinsically safe detectors (Ex-i) with inter-
mediate switching of a Zener
More information about the BX-AIM can be found in the data sheet T 131 436.
