  - TD-109 is a RS-485/422 repeater (also known as RS-485/422 signal amplifier, RS-485/422 signal extender, 485 enhancer), is a professional design of Shenzhen Tiandi Huajie Communication Co., Ltd. to solve the problem of RS-485/422 signal weakness in transmission. The RS485 repeater is industrial-grade design, can extend the RS-485/422 signal 4000 feet (1200 meters) or add 32 connecting points, at the same time has a strong lightning protection and photoelectric isolation protection function, can provide effective protection for both ends of the RS-485/422 equipment. RS485 repeater supports automatic switching between RS-485 bus and RS-422 bus without manual allocation. It is the best choice to enhance RS-485/422 signal.
