R. STAHL Isolator Barriers

Loop-powered binary output

Ex i field circuit

Model: 9276/10-21-60-00k

Art. No.: 261447

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)

Product Description: 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.

Certifications: Ex SIL, IEC 61508, IEC 61511
