This product is unavailable for sale and has been discontinued. Please refer to the replacement items: EDW-100, EDW-120, MD-45 LV, and MDW-45 HV in the Industrial Serial RS-232, RS-422, RS-485 Converters and Repeaters.
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, a wide power range, galvanic isolation, transient protection, and the design of the termination and fail-safe guarantee 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.
