R. STAHL 9176/20-16-00s Loop-Powered Binary Output Isolator
For Ex i field circuits
Art. No. 222184
Product Overview
The R. STAHL Series 9176 binary outputs transmit binary signals for the intrinsically safe operation of Ex i solenoid valves, indicator lamps, and horns. These 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. The two-channel variants feature galvanically separated channels.
- Suitable for solenoid valves and signalling devices
- Two-channel variants reduce the amount of space required
- No need for a separate auxiliary power supply
