I、 Product Introduction
YT-306 is an industrial grade RS-232 signal to RS-485/422 signal to/from interface converter. It is a cost-effective data interface conversion product that can work stably in strong interference environments. It converts a single ended RS-232 signal into a balanced differential RS-485/422 signal to improve anti-interference ability during data transmission, and can extend the RS-232 communication distance to 1.2 kilometers. This product adopts a high-speed optoelectronic isolation design, further improving its anti-interference ability and working stability. It can be powered by an external 9-12V DC power supply, and is equipped with a zero delay automatic transceiver conversion circuit. The unique I/O circuit automatically controls the direction of data flow, ensuring that the program written in RS-232 half duplex mode can run in RS-485/422 mode without modification. The converter transmission rate is 300-115.2Kbps, It can be applied to form a point-to-point, point-to-multipoint remote multi machine communication network between the main control computer, the main control computer, the microcontroller, or peripherals, achieving multi machine response communication. It has the characteristics of small size, long transmission distance, high speed, and stable performance.

YT-306 is designed with aluminum alloy shell, adopts wire pressing terminal interface, and is equipped with pluggable terminal blocks. It is flexible and convenient to use. It is widely used in point-to-point communication, industrial automation control system, power communication control, all-in-one card, Door security, parking lot system, industrial distribution system, various remote control systems, POS cash registers, banks, insurance, securities, canteen food selling system, traffic toll collection system, various PLC, power meter reading Gas meter reading, etc.
