Equipment and systems covered by this certificate are as follows:

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.

The Type KFD2-GU-Ex1 Universal Trip Amplifier comprise a number of electronic components, including an isolating transformer, two opto-isolators, two relays, fuses, resistors and zener diodes all mounted on a single printed circuit board and housed in a plastic enclosure with plug in terminals.

A jack socket is provided in the non-hazardous area circuit to enable the connection of the transmitters to an external programming device.

See Annex for electrical parameters.
