Why choose the RSM232 series isolated transceiver module?
RSM232 series isolated transceivers use power isolation and signal isolation to completely isolate the communication bus and control board.
This not only reduces interference on the bus, but also improves system security and reliability.
Due to its standard baud rate and good EMC characteristics, Zhiyuan Electronics RSM232 series isolated transceivers have been widely used in automotive electronics, instruments, meters, petrochemicals, power monitoring and other fields.

RSM232 series isolated transceivers retain the design concept of traditional isolation circuit, including power isolation, signal isolation, and more importantly, complete test system and advanced technology to ensure product consistency, waterproof, shockproof, long service life, etc. advantage. The potting process protects the board and electronic components from moisture, vibration, overheating, corrosion and radiation, extending the life of the electronic product. The value of using an integrated isolated RS232 communication module to provide customers with discrete component design is shown in Table 1.
