: LB Zone 2
LB Remote I/O for the safe area and Zone 2/Class I, Div. 2
LB remote I/O stations are mounted in hazardous areas Zone 2 or Class I, Div. 2 or Zone 22 or in the safe area. They form a modular signal conditioning system to interface signals from the field with a control system in the safe area. LB Remote I/O connects your conventional sensors and actuators to your DCS using a single standardized fieldbus connection (PROFIBUS, Modbus 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 is easy and adaptable to the needs of your plant concept.
