Numerous process automation applications include basic ON/OFF switching routines. For instance, simple status and alarm indication is noted via beacons, flashlights, sirens, or horns. To control these indicators, solenoid valves, or other switching functions in Zone 1 explosion-hazardous areas, Pepperl+Fuchs provides relay outputs with Ex e terminals.
As part of the FB system remote I/O solution, our relay output modules are available in 2-, 4- and 8-channel versions, giving users the highest flexibility for individual configuration of their remote I/O system.
Galvanic isolation separates the modules’ outputs from bus and power. In addition, the relay outputs are hot-swappable, which allows quick and easy module replacement without time-consuming system shutdowns.
