Isolators
Loop-powered binary output
Ex i field circuit
9276/10-21-60-00k Art. No. 261447
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.
