    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 Digital Input Zener Barrier, 19mA Maximum Current, 1 Channel - MTL7741/RS


    This Zener barrier from Eaton MTL is a safety device that prevents excess energy from entering hazardous areas. It consists of a resistor to manage electrical current, Zener diodes to limit supply voltage and a fuse that protects the diodes from short circuits. The unit uses a changeover relay contact to safely interface between the hazardous area and the safe zone. It has removable terminals that are colour-coded for a quick and simple setup. You can use this Zener barrier to control proximity switches in your industrial setup.

    • Wide operating temperature range of -20°C to +65°C for use in challenging conditions
    • Supply voltage range between 22 and 35V DC for versatility

    How do I mount this Zener barrier?


    To mount this device, simply clamp it onto a DIN rail. This makes installation quick and easy without the need for any specialised tools.

    How many devices can I connect this Zener barrier to?


    As it's a single-channel unit, this Zener barrier is suitable for interfacing with one output device at a time.
