Relay Output

Numerous process automation applications include basic ON/OFF switching routines. 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 2, Class I/Div.2 explosions-hazardous areas, Pepperl+Fuchs provides relay outputs with Ex nA terminals.

As part of the LB system remote I/O solution, our relay output modules are available in 4- and 8-channel versions, ensuring the highest possible utilization of backplanes for module connection while enabling compact remote I/O solutions with large channel numbers.

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.
