FB Remote I/O stations are mounted in Zone 1 hazardous areas. They form a modular signal conditioning system to interface signals from the field with a control system in the safe area. FB Remote I/O connects your conventional sensors and actuators to your DCS using a single standardized fieldbus connection (PROFIBUS, Modbus, Ethernet and others).
The plug-in input and output modules can be hot swapped in a running system without the need for a hot work permit.
There is a wide spectrum of single and multi-channel I/O modules available offering intrinsically safe and increased safety field connections. This ensures that engineering becomes easy and adaptable to the needs of your plant concept.
For dust hazardous area mounting (Zone 21), the system needs to be mounted in a cabinet that meets special specifications: the enclosure must be protected against falling dirt, circulating dust, and windblown dust .
