Details: M-LB-2144
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 is HART transparent.
The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
