Intrinsically Safe Barriers are used to communicate with certain transmitters approved for use in hazardous areas and to provide isolation. Barriers limit the amount of energy allowed to pass into the hazardous area, which inhibit ignition in flammable atmospheres.
    IS Barriers for Vibration Sensors
    The MTL7700 Series follows closely in the footsteps of the MTL700 but as a DIN rail mounting barrier providing quick and easy installation without the need for special hardware. Removable terminals are used for ease of installation, maintenance and for providing a loop disconnect by simply unplugging the terminals from the side of the module. Wire entry is also angled to assist wiring within limited space enclosures. MTL7700 barriers clamp simply and securely onto standard T-section DIN rail, simultaneously making a reliable IS earth connection. For applications where field power is required for switch inputs or 2-wire transmitters, the MTL7700 Series 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.
