Product Description


This series adopts industrial-grade design, large-scale FPGA design, provides 1 serial port, and each port supports RS232/422/485 three business interfaces at the same time. The device is the best choice for connecting the remote terminal unit (RTU) to the host computer (HOST) or distributed data acquisition system (SCADA) controller, with high performance-price ratio. The effective communication distance can reach 0-120KM, and the communication rate of the serial port can reach 0-500KBPS.

Due to the use of optical fiber as the transmission medium, it can completely avoid the threat of lightning, surge, electromagnetic interference and other threats to communication equipment in harsh environments, and at the same time save the investment in lightning and surge protection equipment when using copper wires.

3- Features :

Integrated circuits based on independent intellectual property rights;

  • Provide 1 serial port, and each serial port provides three serial interfaces of RS232/422/485 at the same time (the interface type can be set by DIP switch), which is convenient for opening services on site;
  • Automatic detection and control of RS-485 data flow, no need to use handshake signal to control data flow;
  • Have the ability to automatically detect the baud rate of the serial port signal;
  • Serial data channel can transmit asynchronous serial port data adaptive from 300-500Kbps baud rate;
  • Serial port interface anti-radar to IEC61000-4-5 (10/700μS) differential mode: 6KV impedance (2Ω); common mode: 6KV, impedance (2Ω) standard;
  • Dual DC power supply (5.08 terminal):
  • It can be powered by DC9-55V or AC7-50V wide-range power supply. The power supply has the function of polarity automatic detection, and there is no need to distinguish between positive and negative poles during installation;
  • Support internal isolation, redundant dual power input; anti-reverse protection
  • AC power supply (three-position plum blossom AC seat):
  • Support AC~85-265V AC, or DC110-300V DC wide range input
  • Provide DIN 35mm rail installation, or wall-mounted installation;
