Protection Module
Opis
The protection module 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 circuit voltage during the duration of the overvoltage pulse. Surge protection for 1 signal line, Nominal voltage 1 V DC, Protection module for grounded signal lines, Max. surge current (8/20 µs) 10 kA, Uninterruptable operation (auto reset), Mounting on base module, pluggable, Up to SIL 3 acc. to IEC 61508pa. The device is used in applications where more than 2 signal lines have to be protected, e. g. in applications with 3-wire resistance thermometers or 4-/6-wire measuring bridges. The device is HART transparent. The device is inserted onto the base module and forms the surge protection barrier together with the base module. The device can be replaced without tools by a locking lever.
