R. STAHL 9176/20-15-00s Loop-Powered Binary Output Isolator
Product Type: Ex i field circuit Isolator
Article Number: 222180
Product Overview
The R. STAHL Series 9176 binary outputs are designed for the intrinsically safe operation of Ex i solenoid valves, indicator lamps, and horns. These devices are powered by the control circuit, eliminating the need for a separate auxiliary power supply. The intrinsically safe outputs are galvanically separated from the inputs. Two-channel variants offer galvanically separated channels, reducing the required space.
- Suitable for solenoid valves and signalling devices.
- Two-channel variants reduce space requirements.
- No need for a separate auxiliary power supply.
