MTL7715P+ Dual Channel Relay Output Intrinsically Safe Zener Barrier DIN Rail Mount

The MTL7715P+ is a high-performance 1-channel shunt-diode safety barrier (Zener barrier) from Eaton's Crouse-Hinds series MTL7700 range, specifically engineered for 12V DC systems and high-current applications 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, 50 Ω, 291mA, the MTL7715P+ offers significantly higher current capability than the standard MTL7715+ (which is rated at 150mA), making it the ideal solution for protecting higher-power 12V DC field devices in Zone 0, 1, and 2 hazardous locations (gas groups IIC, IIB, IIA).

• High-Current Design: Safety description of 15V, 50 Ω, 291mA – provides significantly higher current capability than the standard MTL7715+ (150mA)
• 12V DC System Optimization: Specifically designed for 12V DC systems – the ideal barrier for higher-power field devices requiring 12V operation
• Low Series Resistance: Only 50 Ω end-to-end resistance – minimizes voltage drop in 12V DC circuits, maximizing available power for field devices
• IIC Gas Group Certification: Certified for the most hazardous IIC gas groups (hydrogen, acetylene) – suitable for use in Zone 0, 1, and 2 explosive atmospheres
• 291mA Maximum Current: Higher current capability suitable for multiple field devices or higher-power loads
• Removable Terminals – UNIQUE: Unique removable terminal blocks for easy cabling, maintenance, and loop disconnect by simply unplugging terminals from the side of the module
• Bussed Power Capability – UNIQUE: Integrated bussed power distribution reduces cabling requirements when used with the MTL7798 power feed module
• Angled Wire Entry: Wire entry is angled to assist wiring within limited space enclosures
• Ultra-Slim DIN Rail Mounting: Compact 12.6 mm width for standard 35 mm T-section DIN rail mounting
• Dual-Stage Protection: Contains two stages of pulse-tested Zener diodes and an 'infallible' terminating resistor for maximum reliability
• Global Approvals: ATEX, IECEx, UL, CSA certifications for international installation flexibility
