● Based on FPGA design, it can automatically generate a precise RS485 transceiver switch enable signal according to the sent data, and can automatically detect and control the RS-485 data stream. The performance is far better than the ordinary Schmitt trigger enable generation method;
● Unique interface adaptive technology, no need to switch settings, freely switch RS-485/RS-422 interfaces;
● Built-in line short circuit detection and data error detection function, can detect the line A and B short circuit in RS485, or T+ and T- short circuit and R+ and R- short circuit in RS422, and has indicator lights to indicate it, and can detect the received data error ( The data received by some nodes when the connection 0 is greater than the minimum baud rate (300) for the longest connection 0 time);
● RS232-RS485/422 baud rate 300-115.2K and 300-921K adaptive two products are optional;
● Adopting isolation voltage 2500V DC-DC power supply, not using serial port to steal electricity, which improves the applicability of the equipment, and the communication signal is isolated by high-speed optocoupler;
● Serial port interface three-level lightning protection, anti-radar to IEC61000-4-5 (8/20μS) 6KV, impedance (2Ω) standard;
● Wide input voltage range (DC9-55V, AC7-43V), and can automatically detect the polarity of the DC power supply, and built-in self-recovery fuse; support overload protection, anti-reverse protection;
● Meet the requirements of industrial level 4 electromagnetic compatibility;
● Super lightning protection function: lightning protection, anti-inductive high voltage, anti-surge, etc.;
● Rail or wall-mounted installation;
● Wide temperature type: working temperature -40℃~ +85℃;
● All models have passed the 100% baking machine test.
