| DA-149 Series Intrinsically Safe Relay | ||||||||||||||||||
| For isolated signal transfer between safe and hazardous areas | ||||||||||||||||||
| Using the DA-149 intrinsically safe isolating relays, control signals and other data can be exchanged between items of equipment in hazardous areas and between hazardous-and safe-area equipment. The range includes four models, two of which are designed for safe-area location and two of which can be located within hazardous areas. Since the relays need very little power, they do not affect operation of other equipment to which they are connected. Additionally, as inputs and outputs are classified as 'simple apparatus', system certification is not needed. The slimline units are suitable for universal DIN-rail mounting. | ||||||||||||||||||
