FUTEK JK-485YG is an isolation repeater that can realize RS-485/RS-422 signal high-speed isolation relay. By isolating and amplifying the signal, it can extend the RS-485/422 communication distance and anti-interference. Full duplex, half duplex, external +5V power supply. The relay distance is greater than 1.2Km, the rate is: 0~150Kbps self-adaptive.
