R. STAHL 9176/10-16-00s: Loop-Powered Binary Output for Ex i Field Circuits
Art. Nr. 222182
Product Overview
The R. STAHL 9176/10-16-00s is a loop-powered binary output module designed for intrinsically safe operation of Ex i solenoid valves, signaling devices, and horns. It requires no separate auxiliary power, as it is supplied via the control current circuit. The intrinsically safe outputs are galvanically isolated from the input circuits. Two-channel variants offer galvanically isolated channels, reducing space requirements.
- Suitable for solenoid valves and signaling devices
- Two-channel variants reduce space requirements
- No separate auxiliary power required
