Isolated PROFIBUS repeaters, extending a 2 km (9600bps)-long two-way communication distance,rate is 0 ~ 1.5 Mbps.

 E485GP is compatible with Siemens repeater 6 ES7 972-0AA01-0XA0, is the high-speed isolated PROFIBUS repeaters designed for PROFIBUS bus, applicable to all RS485 network such as the PROFIBUS network, PPI network, MPI network, MODBUS network and Free Port communication network. It can realize the signal isolation and amplification. When the RS485 communication distance is over the corresponding baud rates allowing, or nodes on the network are more than the allowed number, you should use repeaters to amplify the signal. The products have characteristics such as extending communication distance, automatically switching the flow of signals and automatically adaptation of baud rate. All their industrial-grade devices are anti-static and anti-lightning, make them work stably in the poor industrial environment.

    When the number of nodes witch connected to the bus is more than 32 or of the connective cable between buses exceeds the maximum length of cable(see table below), you need to use repeaters to amplify signal.
