Product introduction:

ADM-2581 is a 8 RS-485 bus split hub (HUB) designed for the industrial automation communication to solve the RS-485 bus star structure networking and solve the RS-485 system requirements in complex electromagnetic environment. The support speed is as high as 115.2Kbps. The RS-485 interface adopts photoelectric isolation technology and 600W surge protection circuit, providing 1000V isolation voltage, which can suppress lightning and ESD protection. The discriminating circuit used in RS-485 operation mode can automatically perceive the direction of data flow, and automatically switch the enable control circuit to solve the problem of RS-485 transceiver conversion delay.
