What's the 485 repeater for?
485 repeater product features:In the 485 bus, if the 485 transmission line reaches a certain distance and is in a complex external environment, it is vulnerable to external interference such as electromagnetic interference in the external environment. Efficient lightning protection devices in repeaters can effectively suppress lightning (Lightning) and ESD., and provide lightning surge protection power per line of 600W. It can absorb external interference such as electromagnetic induction in external environment. Thus, the stability of the 485 bus is protected.
485 definition of repeater:It is a data relay communication product of isolated RS-485/422, which can relay to extend the communication distance of RS-485/422 bus network and enhance the number of RS-485/422 bus network devices. The 485 bus can be isolated by photoelectricity to prevent common mode voltage interference. Auto switch between RS-485 bus and RS-422 bus can be supported.
485 the use of repeaters:For point to point and point to multipoint communication, industrial control automation, traffic control automation, smart card, access control, attendance, meal selling system, industrial distribution distribution system, CCTV, security systems, POS systems, building automation systems, self-service bank system.
