Function: M-LB-5142
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.
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.
Several hundred products with a SIL/PL assessment, free tools, and brochures in one place: the "Functional Safety Hub" is your starting point when you have to implement safety functions.
The M-LB-5000 surge protection system offers a combination of diagnostics and modularity within a narrow housing design of only 6.2 mm width. Explore the easiest way to protect plant assets …
