Pepperl+Fuchs' FieldConnex process interfaces allow Honeywell to connect multiple intrinsically safe conventional discrete inputs and outputs and temperature inputs to the fieldbus with minimum cabling. Sensors, solenoid valves or temperature sensors can be mounted in Zone 0/ Div. 1, the process interface in Zone 1/ Div. 1. The I/O is powered by the fieldbus, saving on cabling.
Process interfaces allow flexibility through standard function blocks and selections from many types and manufacturers of field instruments.
