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.

  • Mounting/maintenance without a hot work permit
  • I/O modules for Ex i (intrinsic safety) and Ex e field connections
  • I/O modules can be mounted on the backplane in any order
  • 1 - 8 channel I/O modules
  • Standard busses (PROFIBUS, Modbus, Ethernet …)
  • Configuration can be accomplished via the bus
  • HART communication available
  • Optional redundancy for bus and power supply
  • Supports the FDT concept
  • Bus independent SIL 2 shut down outputs available
