DIN rail mounting
safety barriers
MTL7700 SERIES
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.
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.
