IKDRDa-830-430-0

The measuring complex of the pressure switch (IKRD) is designed to provide an electrical signal when a specified pressure or differential pressure is reached. The pressure relays of the IKRD are designed to output an electrical signal when the specified absolute pressure values are reached. The first number after the letters Da, indicates the maximum value of the pressure range. The letter at the end of the cipher indicates the state of the output circuit when the pressure changes from zero to the pick-up point.
