Product Overview
The R. STAHL 9176A series offers loop-powered binary output isolator barriers designed for intrinsically safe operation of Ex i solenoid valves, indicator lamps, or horns. These devices are powered directly by the control circuit, eliminating the need for a separate auxiliary power supply. The intrinsically safe outputs are galvanically separated from the inputs, and two-channel variants feature galvanically separated channels, reducing space requirements.
Key Features and Technical Data
- Explosion Protection: Suitable for various hazardous zones (0, 1, 2, 20, 21, 22) with certifications including ATEX, IECEx, and cFMus.
- Intrinsically Safe Operation: Designed for Ex i field circuits, ensuring safe operation in potentially explosive atmospheres.
- Power: Loop-powered, requiring no auxiliary power supply.
- Safety Integrity Level (SIL): Certified for Safety Integrity Level applications.
- Technical Specifications: Includes detailed data on explosion protection, safety data (voltage, current, capacitance, inductance), electrical data (channels, auxiliary power), galvanic isolation, input/output characteristics, and ambient conditions.
- Mechanical Data: Provides dimensions, weight, enclosure material, and mounting information for DIN rail installation.
- Accessories and Spare Parts: Offers transparent covers for SIL applications and various screw and spring clamp terminals for connection.
Applications
Ideal for use in hazardous environments requiring intrinsically safe signaling and control of solenoid valves, indicator lamps, and horns.
