ZSB-409A 3-Channel Zener Diode Safety Barrier
The ZSB-409A is a 3-channel Zener diode safety barrier designed for intrinsic safety applications in hazardous gas and dust environments. It supports one 24 V DC channel and two 10 V DC channels, making it compatible with Migatron’s RPS-409A-IS, RPS-409A-IS2, and RPS-409A-IS3 ultrasonic sensors. The ZSB-409A provides a safe interface between non-intrinsically safe and intrinsically safe circuits in areas classified as Zone 0, 1, 2, 20, 21, or 22 for ATEX/IECEx, and Class I, II, or III for UL/cUL.
Key Features:
- 3-Channel Design: Includes one 24 V DC and two 10 V DC channels in a compact unit.
- Intrinsic Safety: Ensures safe operation in hazardous areas by limiting the energy supplied to the intrinsically safe apparatus.
- Compatibility: Works seamlessly with Migatron’s RPS-409A series ultrasonic sensors.
- DIN-Rail Mounting: Easy installation on standard 35 mm DIN-rails.
- Certifications: Approved for ATEX, IECEx, and UL/cUL for use in various hazardous locations.
Specifications:
- Supply Voltage: 25.5 V DC max for the 24 V channel; 10.4 V DC max for the 10 V channels.
- Fuse Rating: 50 mA per channel.
- Operating Temperature: -40°C to +60°C (-40°F to +140°F).
- Humidity: 0-95% non-condensing.
- Housing Material: Polyamide, with an IP20 protection rating when installed in an appropriate enclosure.
- Dimensions: 99 mm (L) x 22.5 mm (W) x 114.5 mm (H).
- Weight: Approximately 270 grams (9.5 ounces).
Certifications:
- ATEX: DEMKO 13 ATEX 1214149X
- IECEx: IECEx UL 13.0030X
- UL/cUL: File # E226209, suitable for Class I, II, and III hazardous locations.
The ZSB-409A provides a reliable and compact solution for ensuring the intrinsic safety of your operations in hazardous areas, protecting equipment and personnel while maintaining compliance with international safety standards.
