Pepperl+Fuchs LB1008A Digital Input Module – ATEX/IECEx Zone 2, 8-Channel NAMUR
The Pepperl+Fuchs LB1008A is an intrinsically safe digital input module designed for use in Zone 2 or safe areas. It accepts up to 8 input signals from NAMUR sensors or mechanical contacts, providing reliable signal transmission and fault detection in hazardous area automation systems. With ATEX and IECEx certification, it is a robust solution for process industries requiring safe and continuous operation.
This module features configurable logic (positive or negative), line fault detection, and simulation mode for service operations. Its hot-swappable design allows replacement under voltage, reducing downtime during maintenance. Permanently self-monitoring and galvanically isolated from the power supply and bus, the LB1008A ensures system integrity and operational safety in oil & gas, chemical, and industrial plants.
