As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The Universal Temperature Converter Type KCD2-UT2-Ex1.. is designed to transfer a signal from TC/mV, RTD (2, 3 or 4-wire) or Potentiometer in a hazardous area to unspecified apparatus located in a non-hazardous area. The hazardous area circuit is galvanically isolated from the non-hazardous area circuit using a transformer and opto-couplers and the voltage and current appearing at the hazardous area connectors are limited to intrinsically safe levels. The Universal Temperature Converter Type KCD2-UT2-Ex1.. comprises a number of electronic components including an isolating transformer, two opto-isolators, fuses, zener diodes and resistors all mounted on a single printed circuit board and housed in a plastic enclosure with removable terminals and PowerRail contacts. LEDs provide status indication.
Different versions are identified as follows:
KCD2-UT2-Ex1-*, where * is nothing for a current output or 1 for a voltage output.
See Annex for electrical data.
1. The KCD2-UT2-Ex1.. must be installed in a controlled environment with suitably reduced pollution, i.e. a level of ingress protection of at least IP54.
