MTL4787P+ HIGHER POWER, FOR TWO MULTI-PURPOSE INPUTS/
OUTPUTS 4/20mA transmitters, switches, 4/20mA outputs, solenoids, alarms, LEDs etc.
The MTL4787P+ is a twin 2-channel barrier designed for controller outputs, 4/20mA transmitters (including ‘smart’ versions) and switches.
It is similar to the MTL4787+ but with a lower end-to-end resistance to permit more power to be transmitted into the hazardous area. As each loop generally uses two barrier channels, the module will drive two hazardous-area devices. The MTL4787P+ is designed to pick up bussed power if this is available. The unit incorporates a ‘Schottky’ diode return (as opposed to the MTL4728+ module which uses an earth return). See also the MTL4787+ module.
