DM-485TO485 – RS485 line repeater

When implementing more extensive communication systems, it is often necessary to include an RS485 line repeater into the communication route. It enables extending the total length of the communication route (up to several kilometres), but also creating more complex structures of communication routes (T-connections), galvanically isolating individual communication segments or increasing the total number of stations in the network.

The repeater is designed to be mounted on a 35 mm rail with 24 V DC voltage. The line circuits are equipped with soft overvoltage protections. The repeater works in an automatic mode with transmission rates from 2,400 Bd up to 115 kBd.
