Intrinsically Safe Relay
Oct 02 2009
RTK Instruments’ (UK) DA149 Intrinsically Safe Relays allow control signals and other data to be exchanged between items of equipment in hazardous areas and between hazardous area and safe area equipment.
The range consists of four models, two of which are designed for safe area location and two of which can be located within hazardous areas. The slimline units are suitable for universal DIN-rail mounting.
The DA149 Relays require very little power and therefore they do not 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.
