The Transmitter Power Supply Type KCD2-STC-Ex1.2O* is designed to monitoring signals from equipment in a hazardous area to unspecified apparatus located in a non-hazardous area and communication signals in both directions. The hazardous area circuit is galvanically isolated from the non-hazardous area circuit using transformers and the voltage and current appearing at the hazardous area connectors are limited to intrinsically safe levels. The Transmitter Power Supply KCD2-STC-Ex1.2O* comprises a number of electronic components including four isolating transformer, fuses, zener diodes and resistors all mounted on a single printed circuit board and housed in a plastic enclosure with plug-in terminals for hazardous and non-hazardous area connections. LED indication is provided for power-on status. The following variants are covered by this certificate:KCD2-STC-Ex1.2OKCD2-STC-Ex1.2O.ESKCD2-STC-Ex1.2O.DEKCD2-STV-Ex1.2OKCD2-STV-Ex1.2O.ESKCD2-STC-Ex1.2O(**)-Y1...nKCD2-STV-Ex1.2O(**)-Y1...nSee Annex for electrical data.
1. The KCD2-STC-Ex1.2O must be installed in a controlled environment with suitably reduced pollution.
