High-voltage switching relays

1- or 2-channel


The type HSR1 or HSR2 high-voltage switching relays are used to connect or isolate high-voltage control circuits. This unit is used in all cases where a high degree of galvanic isolation is required for reasons of safety.

The function of the relay therefore does not depend on the polarity.
The relay is installed in a modern plastic housing with the connections at the top and is suitable both for screw fastening as well as for installation on normal carrying rails in accordance with DIN EN 50022.


The magnetic field that is affected by the flow of current in the coil leads to the switching of the inert gas contact that is built into the coil. The display LED lights when the output contact closes. There is no connection between the coil of the relay and the output contact (they are galvanically isolated).
