RTK Instruments’ DA149 intrinsically safe relays allow control signals and other data to be exchanged between equipment in hazardous areas and between hazardous and safe-area equipment.

The range consists of four slimline models, two of which are designed for safe-area location and two of which can be located within hazardous areas.

The units are suitable for universal DIN-rail mounting.

The DA149 relays require little power and therefore do no affect operation of other connected equipment.

The inputs and outputs of these relays are certified equivalent to ‘simple apparatus’, which means they can be included in any intrinsically safe loop without further certification.

The inputs and outputs are galvanically isolated so the relays do not require an earth connection.
