● Integrated circuits based on independent intellectual property rights;
● Provide 2 serial ports, 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 on-site service opening;
● It can automatically detect and control the RS-485 data flow. It is unnecessary to use the handshake signal to control the data flow;
● It has the ability to automatically detect the baud rate of the serial port signal;
● The serial number channel can transmit asynchronous serial port data adaptive from 0-256Kbps baud rate;
● Serial port interface anti-radar to IEC61000-4-5 (10/700μS) differential mode: 6KV impedance (2Ω); common mode: 6KV, impedance (2Ω) standard;
● When 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;
● When 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 or wall-mounted installation.
