Temperature measurement is one of the most safety-critical applications in process automation—especially in explosion-hazardous areas. For this challenging task, Pepperl+Fuchs’ FB system remote I/O solution includes temperature inputs with terminals in type of protection Ex ia.
These signal converters are rated for use in Zone 1 explosion-hazardous areas and allow connection of different resistance thermometers (2-, 3- and 4-wire Pt100 ... Pt1000), thermocouples, and mV signals.
FB system remote I/O temperature inputs are available in the following versions:
The modules support lead breakage detection and short circuit detection. Galvanic isolation separates the inputs from bus and power. In addition, our temperature inputs are hot-swappable which allows quick and easy module replacement without time-consuming system shutdowns.
