MTL7700 range DIN-rail mounting safety barriers 

• Removable terminals

• Bussed power feed to other modules

• Relay and solid state switch modules

• Dual channel variants – 6.3mm per channel

• Proximity detector inputs

• Electronic fusing

• Direct replacement for MTL700 range barriers

• Compatible terminal numbering and safety descriptions

• Since its introduction in 1984 the MTL700 range has established itself as the worldwide standard for safety barriers. Known for its quality and reliability, the MTL700 range is widely used in applications all over the world.

  
  

• The MTL7700 range 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 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 active modules are protected with an electronic fuse for the majority of applications. The MTL7798 active fused, power feed module can protect up to 40 other modules using the bussed power facility and provides a clear indication of a trip condition via a red LED.

The MTL774X range of barriers offer a NAMUR compatible input and a choice of relay or solid state output. The solid state outputs are floating so switching to ground or from a power rail into an input is also possible. The solid state interface also provides a high frequency transfer for use in flow or rotation applications.

Dual channel relay or solid state modules offer the highest packing density with only 6.3mm per channel and when used in conjunction with the power bus, offer users the minimum of wiring with the maximum packing density and the lowest cost per channel.

HOW THEY WORK

All MTL7700 range barriers are based on the same simple principle. Each channel contains two stages of pulse-tested Zener or forwardconnected 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 outputcurrent limiting circuits are employed. All models are certified ‘ia’ for all zones and ‘IIC’ for all explosive atmospheres (except MTL7707P+ and MTL7729P+, 'ia' 'IIB').
