R. STAHL 9176/20-15-00s Isolator Barriers
Loop-powered binary output for Ex i field circuits
Art. No. 222180
Product Overview
The 9176 series binary outputs are designed for intrinsically safe operation of Ex i solenoid valves, indicator lamps, or 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. Two-channel variants offer galvanically separated channels, reducing space requirements.
- Suitable for solenoid valves and signalling devices
- Two-channel variants reduce space requirements
- No need for a separate auxiliary power supply
