Wire breakage monitoring, short-circuit-line monitoring

The devices of the wire breakage detector series DW1 have been developed for monitoring of both driven as well as non driven consumer wires. The proper condition of the wire is signaled through a plus switching malfunction message output, which in case of failure or loss of voltage switches off (closed current circuit).The intact measuring circuit is signaled by a LED in the front panel.

The devices of the wire breakage detector series DW2 have been developed for monitoring of both driven as well as non driven consumer wires. The proper condition of the wire is signaled through a galvanic isolated switch malfunction message output, which in case of failure or loss of voltage switches off (closed current circuit).The intact measuring circuit is signaled by a LED in the front panel.

 Datasheet

The wire breakage monitoring units DW3 have been developed for monitoring wire connections of switch contacts for wire breakage and short-circuit. They are monitoring both N/O as well as N/C contacts. They are used for example for monitoring of alarm contacts in fire detection systems.

 Datasheet

The devices of the wire breakage detector series DW4 have been developed for monitoring of both driven as well as non-driven consumer wires. They correspond in their functioning to the series DW2, but they were optimized especially for flashlights and sirens. (They also can be used for other consumers as for example magnetic valves or resistive loads). Because they have a pulsating current consumption during operation, a wire breakage during driven condition will be signaled after a delay time of ca. 6 seconds, during non-driven operation there is no delay of the report.
