MTL7700 Din-Rail Mounted Barrier.
MTL7700 Din-Rail Mounted Barrier
As a DIN rail mounting barrier, the MTL7700 provides 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 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.
MTL7700 Din-Rail Mounted Barrier
Overview
Known for its quality and reliability, the MTL7700 range of intrinsically safe passive network devices uses Zener diodes, resistors and fuses to safely divert excess electrical energy to ground, preventing sparking or overheating of equipment in hazardous areas.
This helps to ensure a safe working environment and protects people and assets from explosion risks.
Design and installation
As a DIN-rail mounted barrier, the MTL7700 provides quick and easy installation without the need for special hardware. Removable terminals allow easy installation, maintenance and loop disconnection by simply unplugging the terminals from the side of the module.
Angled wire entry assists wiring within limited space enclosures.
Reliable IS earthing
MTL7700 barriers clamp securely onto standard T-section DIN rail, simultaneously providing a reliable intrinsically safe earth connection.
Field power capability
For applications requiring field power for switch inputs or 2-wire transmitters, the MTL7700 range offers a bussed power feed facility. When used with the MTL7798 power feed module, users obtain a fully protected, electronically fused supply to multiple barriers without additional wiring.
