MTL4706+ FOR TWO TRANSMITTERS – 2-wire 4/20mA and 'smart

The MTL4706+ is a 2-channel electronic, over-volt protected barrier. It is designed primarily for energising conventional and smart 2-wire 4/20mA hazardous-area transmitters. As each loop is typically powered by a single channel, the barrier is capable of driving two hazardous-area devices. The novel patented circuit design is notable for extreme accuracy of ±2µA under all conditions. A floating dc power supply is built-in to provide a high voltage output to power the transmitters. The MTL4706+ is capable of operating from bussed power.
