MTL7715+ Eaton MTL Relay Output Zener Barrier

The MTL7715+ is a high-performance 1-channel shunt-diode safety barrier (Zener barrier) from Eaton's Crouse-Hinds series MTL7700 range, specifically engineered for low-voltage AC and DC systems requiring intrinsic safety protection in hazardous areas.

This passive device limits the voltage and current that can reach a hazardous area under fault conditions, preventing ignition of flammable atmospheres. With a safety description of 15V, 100 Ω, 150mA, working voltage of 6V DC and 4V AC, and positive polarity configuration, the MTL7715+ is the ideal solution for protecting low-voltage sensors, switches, and instrumentation in Zone 0, 1, and 2 hazardous locations (gas groups IIC, IIB, IIA).

Note: TIIS certification expired July 2, 2024. New installations in Japan should verify current certification status.

The MTL7715+ is specifically designed for low-voltage system protection in hazardous area installations:

• Oil & Gas: Low-voltage sensor monitoring on offshore platforms
• Chemical Processing: 6V DC and 4V AC circuit protection
• Pharmaceutical: Low-voltage sensor isolation for batch processing
• Power Generation: Turbine monitoring systems
• Factory Automation: Low-voltage proximity sensor protection
• Marine & Offshore: Marine control systems requiring intrinsic safety

• Mounting: Standard 35 mm T-section DIN rail (EN 60715)
• Terminals: Removable screw terminals, colour-coded
• Grounding: High-integrity earth connection via DIN rail
• Wire Entry: Angled for limited space enclosures
• Terminal Capacity: Conductors up to 2.5 mm²
