R. STAHL 9276A Loop-Powered Binary Output Ex i Field Circuit
Article No. 261445
Product Overview
The R. STAHL 9276A is a loop-powered binary output for Ex i field circuits. It emits signals for the operation of intrinsic safety elements such as Ex i solenoid valves, pilot lights, or horns. The devices do not require separate auxiliary power as they are supplied via the control circuit. Intrinsic safety outputs are galvanically isolated from the inputs.
Key Features:
- Extensive catalog for a wide range of solenoid valves
- Space-saving design with a small construction size: 12.5 mm width
- Usable up to SIL 3 (IEC/EN 61508)
