Details: M-LB-4282

Function

The device limits induced transients of different causes, e. g. lightning or switching operations. The limitation is achieved by diverting the current to earth and limiting the signal loop voltage during the duration of the overvoltage pulse.

The device consists of base module and protection module.The protection module can be replaced without tools.

The device has a status indication at the front.

The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
