Our modular remote I/O systems—FB and LB—offer a cost-effective interface for your field signals in the hazardous and the safe areas to your process control system via the fieldbus. A variety of gateways is available for connection to different fieldbusses. Freely combinable I/O modules and high modularity offer cost-saving installations. The remote I/O systems are characterized by high functionality and simple handling.

LB remote I/O stations are mounted in Zone 2, Class I/Div. 2 hazardous areas 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.
- Ex ia approved circuits can be connected to field devices in Zone 1 or Zone 0
- Ex ib is suitable for signals in Zone 1
- Ex ic adapts signals in Zone 2

Supporting Honeywell’s strategy to drive the Universal I/O technology into the market, Pepperl+Fuchs has developed the Universal Input/Output (LB7104A) for the LB remote I/O system.

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.
- Ex ia approved circuits can be connected to field devices in Zone 1 or Zone 0
- Ex ib is suitable for signals in Zone 1
