Waveshare Rail-Mount RS232 to RS485 Type B Active Digital Isolation Serial Converter, Serial Port Conversion for Industrial, Agricultural, IoT, etc

Active electromagnetic isolated RS232 TO RS485 asynchronous bi-directional converter Compatible with RS232/RS485 standard Integrates optional RS485 output terminal 120R resistor, enabled/disabled via a switch The onboard power supply screw terminal, allows 6V~36V DC wide range input

Converting the RS232 signal into balanced differential RS485 signal For interface converting, expanding nodes and long-distance communication Stable Transmission at the Rate of 300~115200bps, about 1200m transmission distance of RS485, about 15m transmission distance of RS232

Onboard power and signal isolation, provide stable isolated voltage, high reliability and strong anti-interference. Onboard Lightningproof Diodes and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic.

Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock proof performance. Industrial rail-mount ABS case design, easy to combine multi rail-mounted serial server together, more freely

The RS232 TO RS485 (B) can be widely used for point-to-point, point-to-multipoint, long distance cascaded communication network between two hosts, or between host and MCU/Peripheral. It also can be used in the application scenarios that require RS232 to RS485 conversion such as Industrial Automation and IoT.
