The Type KFD2-GU-Ex1 Universal Trip Amplifiers are programmable devices designed to interface various temperature sensors located in the hazardous with unspecified apparatus located in the non-hazardous area by limiting the voltage and current to the hazardous area, to intrinsically safe levels. The non-hazardous area circuits are galvanically isolated from the hazardous area circuits.
A jack socket is provided in the non-hazardous area circuit to enable the connection of the transmitters to an external programming device.
