Isolators: Loop-powered binary output
Ex i field circuit
9276/10-21-40-00s Art. No. 261441
- An 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. 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.

Hazardous area vs. Safe area diagram
A schematic illustrating the separation between a hazardous area and a safe area, with connections for input and output signals. The diagram shows the isolator unit with terminals labeled 1, 2, and 3 for the hazardous area side, and terminals labeled 1, 2, and 3 for the safe area side. The loop power is indicated as being supplied from the safe area.
Output characteristic curve
A graph plotting output voltage Uo [V] against output current Io [mA]. The curve shows that at 10 mA output current, the output voltage is approximately 10 V. The open-circuit voltage (Uo) is 21.9 V at 0 mA. The characteristic is generally linear up to approximately 40 mA.
Dimensional Drawings
Detailed dimensions of the isolator unit in millimeters and inches. Key dimensions include: Height: 114.5 mm [4.51 in], Width: 12.5 mm [0.49 in], Length: 112.5 mm [4.43 in]. The drawing also shows a reference to the ISpace Series 9260, 9265, 9270, 9275, 9276, 9282 with screw terminals.
