The status output is a potential free, opto-isolated normally c
losed solid-state
relay. This can be congured to monitor various alarm events within the NE804
unit, see NEOS User Manual. An external load in series with an external voltage
source is required for proper functionality. For voltage/current ratings, see Interface
specications section.
The Digital in is an opto-isolated digital input which can be used to monitor external
events. For voltage/current ratings, see Interface specications section.
