Industrial RS232 TO RS485 Converter

Industrial Grade Isolated RS232 TO RS485 Asynchronous Bi-Directional Converter
Embedded TVS (Transient Voltage Suppressor) And Lightning-Proof Diodes


Features At A Glance

  • Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal
  • Stable transmission on rate of 300~115200bps
  • Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
  • Onboard unibody ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
  • Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock resistance
  • Integrates optional RS485 output terminal 120R resistor, enabled/disabled via switch
  • DC-005 power jack, allows 6V~36V DC wide range input, suits different application situations
  • 3x LED indicators, easy to check the operating status: power, transmitting, and receiving
  • Aluminium alloy enclosure with sand blasting and anodic oxidation, solid and durable
