Isolators

Loop-powered binary output

Ex i field circuit

Model: 9276/10-24-48-00s

Art. No.: 261442

An extensive portfolio for a wide variety of solenoid valves

Slim design saves space – just 12.5 mm wide

For use up to SIL 3 (IEC/EN 61508)

The Series 9276 binary outputs transmit signals for the intrinsically safe operation of Ex i solenoid valves, indicator lamps and horns. The devices do not require a separate auxiliary power supply as they are powered by the control circuit. The intrinsically safe outputs are galvanically separated from the inputs.
