Description
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 beyond 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 configurations by DIP switch.
The RD-48 is designed for use in heavy-duty industrial applications, with a 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.
End of Life Product - No Replacement
Please note that the RD-48 HV has been phased out. You can explore the EDW-100, EDW-120, MDW-45 HV, and MDW-45 LV in the Serial Converters and Repeaters.
