R. STAHL 9276A Loop-Powered Binary Output Ex i Field Circuit

Article No. 261446

Product Overview

The R. STAHL 9276A is a loop-powered binary output designed for Ex i field circuits. It is used to emit signals for the operation of intrinsically safe Ex i solenoid valves, pilot lights, or horns. The device does not require separate auxiliary power as it is supplied via the control circuit. The intrinsic safety outputs are galvanically isolated from the inputs.

Key features include:

Extensive catalog for a wide range of solenoid valves.
Space-saving design with a small construction width of 12.5 mm.
Usable up to SIL 3 (IEC/EN 61508).
