MTL7000 Series award-winning,intrinsic safety shunt-diode safety barriers are innovative devices designed to provide exceptionally high packing densities, straightforward‘single-operation’ installation and simplified connection, commissioning and maintenance facilities. Many of the MTL7000 Series features duplicate the functions of conventional field terminals and the barriers can, therefore, “double up”as terminals for many applications, saving even more space. 

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

MTL7798 Power feed and protection module

The MTL7798 power feed module incorporates both voltage and current sense mechanisms to protect barrier circuits by activating a solid state trip mechanism when fault or overload conditions occur in the power source circuit. Resetting the module after tripping is

achieved by interupting the supply to the unit. A red LED indicates a circuit trip condition and a green LED the availability of power at the outputs. Bussed power for other modules is sourced from the top of the unit using the Bus Power Link BPL7700 or via terminals 1 and 2.

ADDITIONAL SPECIFICATION 

Input voltage range (terminals 5&6) 20 to 26.8V 

Maximum input voltage capability 45V 

Power source requirements >1.8A 

Trip mechanism Minimum trip 26.8V @ 20°C (+18mV/°C) 

Output current range 0 to 800mA 

Maximum voltage drop 20mV @ 0mA, 1.0V @ 800mA load

The MTL7798 power feed module would normally be used with standard barriers such as MTL7787+ and MTL7787P+ because the current/voltage trip protection mechanism of the MTL7798 protects the fuses in the barriers.
