Equipment and systems covered by this certificate are as follows

The Type KCD2-SR-Ex*.* Switch Amplifiers are designed to transfer digital signals from the hazardous area to unspecified apparatus located in the non-hazardous area. The voltage and current passed to the hazardous area are limited to intrinsically safe levels and have linear characteristics. Up to two hazardous area channels are fitted and are galvanically isolated from the non-hazardous area circuit using transformers.

The Type KCD2-SR-Ex*.* Switch Amplifier comprise a number of electronic components, including isolating transformers, fuses, zener diodes and resistors all mounted on a single printed circuit board and housed in a plastic enclosure with polarised plug-in terminals for hazardous and non-hazardous area connections. The non-hazardous area connections are via relay contacts with configuration switches allow the setting of the direction of operation and lead monitoring. LED indication is provided for power-on and channel status.

There are three models of the Type KCD2-SR-Ex*.* Switch Amplifier, the Type KCD2-SR-Ex2 Two Channel Switch Amplifier, the Type KCD2-SR-Ex1 Single Channel Switch Amplifier and the type KCD2-SR-Ex1.LB Single Channel Switch Amplifier. The Types KCD2-SR-Ex1 and KCD2-SR-Ex1.LB are depopulated versions of the KCD2-SR-Ex2 with only one hazardous area channel.
