R. STAHL Series 9276 Loop-Powered Binary Output Isolator
Model: 9276/10-21-60-00s
Art. No.: 261443
Product Type: Ex i field circuit loop-powered binary output isolator
Key Features
- Extensive portfolio for a wide variety of solenoid valves
- Slim design, only 12.5 mm wide
- Suitable 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 are powered by the control circuit and do not require a separate auxiliary power supply. The intrinsically safe outputs are galvanically separated from the inputs.

Technical Drawings
Output Characteristic Curve
The diagram shows the relationship between output voltage (U) and output current (I.) for the 9276/10-21-60-00s model. The output voltage ranges from 0V to approximately 30V, and the output current ranges from 0mA to 60mA. Key points shown are the open-circuit voltage of 21.9V and a voltage of 12.9V at a current of approximately 58mA.
Diagram Description: A graph with 'output current I. [mA]' on the x-axis (0 to 60) and 'output voltage U [V]' on the y-axis (0 to 30). A line representing the output characteristic shows a steep rise from the origin, leveling off around 21.9V. A specific point is marked at approximately 58mA current and 12.9V voltage.
