I. Product Introduction
YT-6204 is a 4-port industrial grade optical isolation RS-485 hub. The YT-6204 4-port optical isolation 485 hub can provide a more flexible RS-485 star bus structure. The RS-485 interface input and output terminals are independently driven, changing the original single bus structure to a network structure, bringing great benefits to engineering construction and system stability. Industrial grade photoelectric isolation: Provide 2.5KVrms photoelectric isolation for all RS-485 interfaces, effectively solving transmission problems caused by external lightning surges and ground potential differences. Automatic control of data flow, solving data flow problems through hardware, automatically identifying and controlling the direction of data transmission. Equipped with short circuit and open circuit protection function, RS-485 port fault alarm function, and the ability to automatically cut off the fault port. This design ensures that when the RS-485 port device connected to it fails, the faulty RS-485 port will be isolated to ensure the normal operation of other network segment devices
YT-6204 is designed with flame-retardant plastic shell, with crimping terminal interface, and 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, 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 charging system, various PLC, data Electricity meter Gas meters, etc.
