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.
To permit the following: -
i) Minor changes to the circuit and PCB layout.
ii) Minor changes to the construction of the transformer.
iii) Use of alternative TOC2 opto-coupler.
iv) Re-definition of component references.
v) The changing of the listed Manufacturer to: -
