Eaton MTL7707P+ Intrinsically Safe Zener Barrier
The Eaton MTL7707P+ Intrinsically Safe Zener Barrier is a dual-channel intrinsically safe zener barrier engineered as associated apparatus for hazardous-area applications. It is designed to protect field-installed instruments in Zone 0, Zone 1, and Class I Division 1 locations by limiting electrical energy and preventing ignition risks, while the barrier itself is installed in the safe area or non-incendive locations.
Part of the proven MTL7700 Series, the MTL7707P+ provides reliable voltage and current limiting with integrated electronic overvoltage protection, allowing safe connection to unregulated DC power supplies. Its compact DIN-rail design, removable terminals, and robust construction make it ideal for demanding industrial environments where intrinsic safety compliance and long-term reliability are critical.
Key Features:
✅ Intrinsically safe zener barrier (associated apparatus)
✅ Two independent channels for signal protection
✅ Electronic overvoltage protection for unregulated DC supplies
✅ DIN-rail mountable for control panels and marshalling cabinets
✅ Suitable for switches and controller output circuits
✅ Removable terminals for easy installation and maintenance
✅ Compact design for high-density installations
