HK-5112RS-485HUB provide Star RS-485 bus. Each port has a short circuit, open circuit protection . Optical isolation 2500V, users can easily improve the RS-485 bus architecture , split segments, improve communication reliability. When lightning strikes or equipment failure occurs, the problem of the network will be isolated in order to ensure the normal operation of other segments . This greatly improves the performance of existing RS-485 network reliability, effectively shortening the network maintenance time. Rational use HK-5112RS-485HUB can help you design a unique highly reliable RS-485 systems .
