R. STAHL 9176/10-16-00k: Loop-Powered Binary Output for Ex i Field Circuits
Article Number: 222183
Product Overview
The R. STAHL 9176/10-16-00k is a loop-powered binary output module designed for the intrinsically safe operation of Ex i solenoid valves, signal lamps, or horns. This device does not require a separate auxiliary power supply, as it is powered via the control current circuit. The intrinsically safe outputs are galvanically isolated from the inputs. Two-channel variants offer reduced space requirements and feature galvanically isolated channels.
- Suitable for solenoid valves and signal devices
- Two-channel variants reduce space requirements
- No separate auxiliary power required
