Designed to facilitate the connection of traditional input and output signals onto a bus network, Pepperl+Fuchs has introduced the LB/FB remote I/O systems.

LB/FB systems support general-purpose or intrinsically safe applications with modules that can be mixed and matched on the same backplane.

These systems facilitate connection to Profibus DP, Modbus and Foundation fieldbus for all traditional signal types, including discrete, analogue, frequency and temperature.

Redundancy for the communication interface and power supply ensures high reliability.

‘Anyone using a traditional intrinsic safety barrier can benefit from LB/FB remote I/O systems, as they allow barriers to be pushed into Division 2 and Zone 1 hazardous areas,’ said Brian Traczyk, Pepperl+Fuchs product manager.

‘These remote I/O systems are also suitable for upgrades and expansions and can be beneficial when devices such as thermocouples or RTDs do not have a fieldbus interface,’ he added.

LB/FB remote I/O system users are said to benefit from: reduced wiring; fewer DCS control cards; fewer terminations for reduced installation costs; and reduced control cabinet space requirements.

Faster commissioning LB systems are rated for Division 2 mounting with inputs and/or outputs mounted in a Division 1/Zone 0 area.

FB systems are designed for intrinsically safe or increased safety applications and rated for Zone 1 mounting with inputs and/or outputs mounted in a Zone 0 area.

With LB systems, IS and general-purpose modules can be mixed and matched on the same backplane.

LB systems include a backplane, communication interface, power supply and I/O modules.

They can be DIN Rail mounted or Pepperl+Fuchs’ Systems and Solutions Group can pre-mount the system in an enclosure specified by the user.

With FB systems, IS and increased safety modules can be mixed and matched on the same backplane.

FB systems include a backplane/enclosure, communication interface, power supply and I/O modules.

The system comes installed in the user’s choice of enclosure with GRP, fibreglass and stainless steel as standard options.

FB systems are available with a number of optional accessories that can be mounted within the enclosure to extend its functionality, including terminal blocks, fuses and disconnect switches.
