BX-IOM input/output module connection
The BX-IOM has a galvanically isolated output for actuating monitored consumers (e.g. sirens) which are supplied by external
voltage sources. The input can be used to poll potential-bound voltage sources. The monitored output is divided into three
load ranges and can actuate and monitor a load between 20
Ω
and 1 k
Ω
.
Further information about the BX-IOM can be found in the data sheet T 131 461.
