Multidrop fiber optic converter ADA-7240 is a device that allows to construct of fiber-optic networks, used for connection of devices with RS485/422
interface, far removed from each other such as halls, buildings and other objects. Optic signal conversion to RS485 /RS422 takes place without interference with the
data format. The use of fiber optics provides complete isolation between connected devices and resistance to interference on the transmission bus. The fiber
connection is implemented by a line consisting of two fibers. The ADA-7240 can be used for extend fiber optic bus by a distance 2500m because it is also the fiber
The converter is equipped with screw terminal for RS485/422 connections and power supply. Supports asynchronous transmission with baud rates up to 2Mb/s on
RS485 2-wire or 4-wire via one or two twisted pair. The device use to operate lines RX +, RX-, TX + (A), TX- (B). To RS485 bus built on the ADA-7240 can be
connected 32 devices operating in half duplex mode or 2 devices operate in half duplex mode on RS422 bus. Overvoltage protection was made on base safety diodes and fuses on each RS485/RS422 lines.
