Remote I/O Systems

Our modular Remote I/O systems - FB, LB, and RPI - 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 are available for connection to different fieldbuses. 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.

FB Remote I/O for Zone 1/21

FB Remote I/O stations are mounted in Zone 1 or Zone 21 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

LB Remote I/O for the Safe Area and Zone 2/22

LB Remote I/O stations are mounted in Zone 2/22 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

Remote Process Interface (RPI) for the Control Room and Zone 2/22

RPI stations are mounted in Zone 2/22 hazardous areas or in the safe area. They form a modular signal conditioning system to interface all kinds of signals from the field with a control system that is located in the safe area. The modules are based on K-series enclosures to fit on a DIN rail.
