Transtech Electronic Controls offers a comprehensive range of intrinsically safe (IS) barriers and Zener barriers designed to safeguard electrical circuits in hazardous environments. They can be installed either in safe zone or hazardous zone, realizing transmission of 4-20mA signal from safe zone to the hazardous area and vice versa. These barriers limit voltage and current, preventing potential ignition sources in explosive atmospheres. These IS barriers can be seamlessly integrated into industrial control systems while maintaining compliance with international safety standards such as ATEX, IECEx and SIL certification.
Key features & Benefit:
- Compatible with standard 4-20mA signals for industrial applications.
- Effectively limit voltage and current for intrinsically safe applications
- Durable and reliable for long-term performance in harsh environments.
- Slim, compact design for seamless integration into control panels.
- Certified for hazardous area applications such as ATEX and IECEx.
Key Applications of Intrinsically Safe Barrier:
- Oil and Gas: explosion-proof barrier in offshore platform and refineries
- Mining: protecting critical assets and instrumentation
- Chemical and Pharmaceutical: preventing ignition of volatile components
- Industrial automation: safe operation of process control systems
