Special Features

  • [Industrial chip] Adopting industrial chip SP3485 to realize mutual conversion of TTL level and RS422/485, high-speed communication, stable and reliable, good compatibility, baud rate support range: ≤ 2M bps (experimental environment).
  • [Line Optimization] Power supply isolation and signal isolation independently, using 5.08mm plug-in terminals, smooth plugging and unplugging, sturdy and reliable, the use of the TTL terminal requires 5V power supply, signal output with the same voltage.
  • [Protection upgrade] The TTL terminal has overcurrent protection and surge protection to ensure stable output of current and voltage, and strong shock resistance, while the RS485 terminal is equipped with overcurrent protection, surge protection and lightning gas discharge protection circuit.
  • [Detailed Optimization] On-board automatic send/receive conversion circuit, no need for “send/receive” control. Three on-board LEDs for power, transmit and receive to visually display circuit status. Supports 3.3V TTL level inputs
  • [High Quality Components] Customized PCB board, machine mounted, accurate positioning holes, 120R termination resistor pad reserved on board to increase signal transmission stability and reduce interference, metal case with frosted finish.
