Relay coupler is mainly made of small electromagnetic relay.It's terminal -type module joggle of indication and protective function.Widely used in the joggle among peripheral equipment, control signal and adjustable equipment automatically contrilled to come true matching of electric frequency and powder.
our company tires to provide various specs relay couplers applying to different voltage and power in the applicable field. Character of product is minimum modularization. Install it on the standard NS 35/7.5 or NS32 lead rail and it is possible to use safely, reliably and conveniently.
In concrete application, contact switch of relay is in DC or AC return circuit. when cutting it off, produce highter inductive voltage in load of inductor and capacitor, and damage contact. In order to delay life of relay, it is possible to use above protective measure lots of manufactures of contactor and electromagnetic valve etc. have had necessary protective elements to sell. when choosing and using it . Pay attention to their merit and defect to use it reasonably.
