R. STAHL Series 9276 Isolators
Loop-powered binary output, Ex i field circuit
Art. No.: 261445
Model: 9276/10-21-40-00k
Key Features
- 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. These 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.
