3-Channel Zener Safety Barrier ZSB-409A
Reliable Intrinsic Safety Solution for Hazardous Environments
The 3-Channel Zener Safety Barrier ZSB-409A is designed for intrinsic safety applications in hazardous gas and dust environments. It supports one 24 V DC channel and two 10 V DC channels, ensuring compatibility with Migatron’s RPS-409A-IS, RPS-409A-IS2, and RPS-409A-IS3 ultrasonic sensors. This safety barrier provides a secure interface between non-intrinsically safe and intrinsically safe circuits, suitable for Zone 0, 1, 2, 20, 21, or 22 (ATEX/IECEx) and Class I, II, or III (UL/cUL) hazardous locations.
Key Features:
- 3-Channel Compact Design – Combines all connections in one space-saving unit with one 24 V DC and two 10 V DC channels.
- DC Positive Polarity – Ensures seamless compatibility with Migatron’s RPS-409A series ultrasonic sensors.
- Intrinsic Safety – Limits energy supplied to intrinsically safe apparatus for safe operation in hazardous areas.
- Grounding and Safety – Features an insulated grounding wire and must be installed in safe areas like control cabinets.
- Easy Installation – Designed for 35 mm DIN-Rail mounting with Control Drawing No. Ex05121109 for installation guidance.
- Certifications – Approved for ATEX, IECEx, and UL/cUL for use in diverse hazardous locations.
Applications:
- Hazardous Gas and Dust Environments – Ideal for industrial settings prioritizing safety.
- Ultrasonic Sensor Integration – Perfect for applications requiring reliable sensor performance in hazardous areas.
- Indoor and Outdoor Use – Suitable for use in both environments when installed in appropriate enclosures.
