MTL7000 Series MTL discontinued range model MTL7028+ slimmest barrier, we still have some pieces in stock to supply.

Controller outputs (I/P converters)

The single-channel MTL7028+/7128+ with a voltage drop of 6.7V/6.9V is the recommended choice for most controller outputs. Higher-power versions are available: the MTL7128P+ (5.5V drop) is suitable for IIC applications; the MTL7129P+ (4.22V drop) for IIB applications. 

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.

A barrier width of only 7mm enables maximum packing densities due to the use of surface mount and thick-film hybrid circuit technologies

(subjects of patent applications).
