Product introduction
ADM-2720 is designed for industrial automation communication, solve the signal RS-232 interface into a photoelectric isolation converter of RS-485/422 signal, support the maximum transfer rate up to 115.2Kbps, RS-485 interface adopts photoelectric isolation technology, 600W surge protection circuit to provide isolation voltage 1000V can effectively suppress the protection and ESD. The discriminating circuit used in the RS-485 working mode can automatically perceive the direction of data flow, and automatically switch the enabling control circuit, so as to solve the problem of RS-485 transceiver conversion delay easily. The transmission distance of the RS-485 interface is more than 1000 meters, and the performance is stable. Widely used in highway toll collection system, road monitoring system and power collection system areperformance data conversion products.
