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

RS232 TO RS485 (B) is an industrial-grade rail-type active optoisolated RS232 to RS485 converter.


  1. Industrial Automation
  2. Access control
  3. Self-service banking
  4. Parking services
  5. highway toll stations
  6. Attendance system


  1. Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal
  2. Stable transmission at the rate of 300~115200bps
  3. Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
  4. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
  5. Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
  6. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
  7. Integrates optional RS485 output terminal 120R resistor, enabled/disabled via a switch
  8. The onboard power supply screw terminal allows 6V~36V DC wide-range input
  9. Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective


  1. Connector: screw terminal
  2. Transmission distance: about 15m
  3. Transmission mode: point-to-point


  1. Connector screw: terminal
  2. Direction control Hardware automatic control
  3. Protection 600W: lightning proof and surge-suppress, 15KV ESD protection
  4. Terminal resistor: 120R, enabled/disabled via a switch
  5. Transmission Distance: About 1.2km
  6. Transmission Mode: point-to-multipoint (up to 32 nodes, it is recommended to use repeaters for 16 nodes or more)
