R. STAHL Isolator Barriers

Loop-powered binary output

Ex i field circuit

9276/10-24-48-00k Art. No. 261446

Key Features

A comprehensive portfolio for a wide range of solenoid valves
Space savings due to a slim design – 12.5 mm wide
Can be used for functional safety levels up to SIL 3 (IEC/EN 61508)

Series 9276 digital outputs issue signals for the intrinsically safe operation of Ex i solenoid valves, indicator lamps or 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.
