Currently, isolated communication modules include the CTM series of isolated CAN transceivers, such as the CTM8251T. RSM series isolated RSM-485 transceivers, such as RSM485HCHT, retain the design concept of traditional isolation circuits, including power isolation and electrical isolation. More importantly, the perfect test system and advanced technology ensure product consistency, with many advantages such as waterproof, shockproof and extended service life. For example, the potting process can continuously protect the circuit board and electrical components from the effects of moisture, vibration, overheating, corrosion and radiation.
