Description
The DA (UL) series of normally open, high voltage relays offers an isolation voltage of 7.5kV with contact resistance as low as 15mΩ (typical for Rhodium contacts). These relays utilise high vacuum reed switches to achieve their excellent characteristics, and are available in choice of Rhodium or Tungsten contacts – the Rhodium contacts offer lower contact resistance, while the Tungsten handles higher switching voltages. The DA (UL) series of relays is offered as PCB and panel mountable with variety of connection options. The series has been UL approved as per pollution degree 2 classification. The DA (UL) series offers a working temperature range from -20°C up to +70°C.
