● RS232 RS485 to 4 Ports RS485 repeater/hub. This is a RS485 repeater / hub specially designed for industrial automation communication. It solves the networking of RS485 bus star structure and the requirements of RS485 large system in complex electromagnetic environment.

● It supports transmission rate up to 115.2kbps, and adopts optical isolation technology in the RS485 terminal. High performance transient voltage suppressor, 600W protect against surges circuit,Providing 1000V isolation voltage can effectively ESD protection. It effectively optocoupler isolate the RS485 signal from the main and auxiliary ends, and has 4 independent isolated auxiliary stations. Effectively do power supply isolating between the main port and the auxiliary port.

● The built-in conversion processor automatically senses the direction of data flow. Automatically judge the channel status, automatically switch the enabling control circuit,It is easy to solve the delay problem of RS485 transceiver conversion.No jumper setting is needed to realize full asynchronous half duplex (RS485) mode conversion.Plug and play.

● Signal isolation, power isolation, two-way transmission, enhanced anti-interference, extended communication distance. Support multiple device hand-in-hand connections, or multiple device cascade connections networking. It is easy to install. It can be installed by 35mm standard guide rail or other ways (Not included 35mm guide rail).

● The RS485 terminal transmission distance is more than 3000 meters, stable performance. Adopt external power supply, safe and reliable, suitable for outdoor, provide DC 9 ~ 40V wide voltage input. Widely used in highway toll system, road monitoring system and electric power collection system, it is a data communication product with excellent performance.
