• For Foundation™ fieldbus networks inhazardous areas

• Mount in Zone 1 (gas) with spurs connected into Zone 0

• Easy mounting via DIN-rail or panel fixing

• Compatible with FISCO and Entity-certified fieldbus instruments

• Compact, modular construction

• Optional, integrated surge protection for trunk and spurs

The 9377-FB3-Px Fieldbus Barrier module is a further enhancement

of the established 937x product range, and provides a compact

and economic solution for Foundation fieldbus networks in

hazardous area applications. The field-mounted barrier receives

power and FOUNDATIONTM fieldbus H1 communications via

a non-intrinsically safe trunk and converts this to a number of

galvanically isolated, intrinsically safe, spur connections.

The trunk terminals are implemented as increased safety (Ex e)

and the spur terminals as intrinsically safe (Ex ia) for connection

to IS fieldbus instruments in IIC, Zone 0 hazardous areas.  The spur

connections are compatible with both FISCO and Entity-certified

field instruments.
