R. STAHL Isolator Barriers

Loop-powered binary output for Ex i field circuit

Model: 9176/20-15-00k | Art. No. 222181

Key Features

Suitable for solenoid valves and signalling devices
Two-channel variants reduce the amount of space required
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. The devices are powered by the control circuit and feature intrinsically safe outputs that are galvanically separated from the inputs. Two-channel variants have galvanically separated channels.
