Features

  • Onboard Original FT232RL and SP485EEN chip. Fast communication, stable and reliable, better compatibility.
  • Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal.
  • Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, and low power consumption.
  • Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic.
  • Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, and improve shock resistance.
  • Onboard 15KV ESD isolation protection and 600W lightning-proof & anti-surge protection.
  • Onboard 120R terminal resistor on the RS485/RS422 ports, enable by default, configurable by jumper.
  • 3x LEDs for indicating the power and transceiver status.
  • Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective.
