    Intrinsic Safety Barriers - Eaton MTL 7700 Series


    The MTL7700 Series of intrinsically safe passive network devices use zener diodes, resistors and fuses to safely divert excess electrical energy to ground and prevent sparking or overheating of equipment in hazardous areas.

    The MTL7700 intrinsic safety device provides quick and easy installation and maintenance with removable terminals, the loop can be disconnect by simply unplugging the terminals from the side of the module. Wire entry is also angled to assist wiring within limited space enclosures.

    DIN-rail mountable the MTL7700 intrinsic safety devices clamp simply and securely onto standard T-section DIN rail, simultaneously making a reliable intrinsically safe earth connection.

    For applications where field device power is required for switch inputs or 2-wire transmitters, the MTL7700 barrier range provides a bussed power feed facility. When used in conjunction with the MTL7798 power feed module the user has a fully protected, electronically fused supply to many barriers with no additional wiring required.

    All MTL7700 range zener barriers are based on the same simple principle. Each channel contains two stages of pulse-tested Zener or forward-connected diodes and an ’infallible’ terminating resistor. In the event of an electrical fault in the safe area, the diodes limit the voltage that can reach the hazardous area and the resistor limits the current. A fuse protects the diodes, and the two stages of voltage limitation ensure continued safety if either stage should fail. No active output current limiting circuits are employed. All models are certified ’ia’ for all zones and ’IIC’ for all explosive atmospheres (except MTL7707P+ and MTL7729P+, 'ia' 'IIB').

    Eaton MTL Zener Barrier with Analogue Input, 200mA , 6.7V DC - MTL7700 Series - MTL7760AC/RS


    Mitigate the risks of control and process instrumentation with this Eaton MTL zener barrier. It's an intrinsic safety device that prevents sparking and overheating that may cause fire outbreaks and electric shocks. Removable terminals make this barrier simple to install and maintain. You can disconnect loops by simply unplugging the terminals from the side of the module and angled wire entry means installation is straightforward even where space is limited. Use this device with applications that have switch inputs or 2-wire transmitters.

    Features & Benefits


    • DIN rail mounting capability makes this zener barrier easy to install and service. It also lets you establish a reliable intrinsically safe earth connection
    • Suitable for use in demanding industrial applications thanks to a wide operating temperature range from -20°C to +60°C
    • Designed and tested for safe use in explosive settings

    Why do I need a zener barrier?


    Zener barriers process standardised electrical signals. When excess signals (or power input) are detected, these barriers divert them into a defined hazardous area to safeguard equipment, operations and people.
