R. STAHL 9176 Series Loop-Powered Binary Output Isolator Barriers
Product: Loop-powered binary output
Application: Ex i field circuit
Model Numbers: 9176/10-16-00s
Article Number: 222182
Brand: STAHL
Key Features
- Suitable for solenoid valves and signalling devices
- Two-channel variants reduce space requirements
- No need for a separate auxiliary power supply
The 9176 series binary outputs issue binary signals for the 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 feature galvanically separated channels.
