The RD-48 is a multi-purpose device that allows the extension of networks beyond the normal scope of the RS-422/485 standards. The device can be used as a repeater to extend the maximum distance of a network beyond 1200 m or the number of devices above 32. It can also swap between 2 and 4 wires or be used to build a structured and isolated network.

The device is simple to install with its purpose built integral DIN clip and with all configuration by DIP switch. The RD-48 is designed for use in heavy duty industrial applications, the wide power range, galvanic isolation, transient protection and the design of the termination and fail safe guarantees communication in the worst environments.

When the RD-48 is used as a repeater it automatically detects the data direction, regenerates and retransmits the data according to the RS-422 or RS-485 standard. The repeater also has support for some Manchester coded synchronous protocols.
