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 in-
termediate switching of a
Zener
barrier. An output for a repeat signal is also available.
Further information about the BX-AIM can be found in the data sheet T 811 100.
