Applications
ISO7421DR is widely used in industrial automation systems where signal isolation is required between microcontrollers and high-voltage field devices such as sensors, actuators, and motor drives. It is also applied in medical equipment, power converters, and communication interfaces (RS-485, CAN) where ground potential differences or high common-mode noise necessitate galvanic isolation. Additionally, it serves in smart metering and gate driver circuits to protect sensitive digital logic from high-voltage transients.
