Description
The voltage monitorrelay with reset has outputs for indicator/buzzer (signal horn) e..g.
It switches an acoustic or optical signal when a defined voltage exceeds or under-run.
Application Example
Analog value check e.g. pressure check.
Function Under-running the lower voltage threshold at terminal 15 the outputs 87, 87a and c are switched on. By reset input x the output 87 can be switched off again, the outputs 87 a and c stay on. Is the upper voltage threshold exceeded, all outputs are switched off. Other voltage thresholds are availlable on demand.
For different housing please see in the chapter housing and baseplates.
