Output Alarm relay (status) contact
The Status output is a potential free, opto-isolated normally closed solid-state relay. This can be configured to
monitor various alarm events within the RFIR unit, see WeOS Management Guide. An external load in series
with an external voltage source is required for
proper functionality. For voltage/ current ratings,
see Interface specification section.
The Digital in is an opto-isolated
digital input which can be used
to monitor external events.
