The Volt­age Mon­i­tor Relay With Reset (ac­knowl­edg­ment) has out­puts for a sig­nal, buzzer or other in­di­ca­tors. It can be used to turn on/off acoustic or op­ti­cal warn­ing sig­nals when the input volt­age drops below/ex­ceeds a de­fined volt­age level.

Function

When the input volt­age ap­plied to ter­mi­nal 15 drops below the de­fined thresh­old volt­age out­puts 87, 87a, and C are turned on. Out­put 87 can be switched off again via reset input x (ac­knowl­edge­ment) while out­puts 87a and C re­main on.
When the input volt­age on ter­mi­nal 15 ex­ceeds the de­fined thresh­old volt­age all out­puts are switched off. Cus­tom thresh­old volt­ages are avail­able on re­quest.

Please refer to the chap­ter hous­ing and base plates for ad­di­tional hous­ing op­tions.
