Photoelectric isolation industrial grade RS-232 to RS-485 / 422 converter
RS-232, RS-485 / 422, three terminal isolation of power supply

product description

ADM-2721 is a product designed to solve the problem of weak signal and easy interference when the RS-485 / RS-422 signal is transmitted over an extended distance. Can extend the communication distance of RS-485 / RS-422 bus, increase the number of devices in RS-485 / RS-422 network, support transmission rate group up to 115.2KBPS, the product has built-in three-terminal isolation, RS-485 / RS- The 422 and power are isolated from each other. The RS-485 interface uses photoelectric isolation technology. The 600W lightning protection circuit provides a 1500V isolation voltage, which can effectively suppress lightning and ESD protection. The discrimination circuit used in the RS-485 working mode can automatically sense the direction of the data flow, and the automatic switching enables the control circuit to easily solve the RS-485 transmission and reception conversion delay problem. The RS-485 interface has a transmission distance of more than 1000 meters and stable performance. Widely used in highway toll system, road monitoring system and power collection system, it is a data interface conversion product with excellent performance and good price.
