The DCC302(RS485 Isolated Repeater) is an optically isolated RS485 to RS485 line repeater that can be used to isolate a piece of equipment from the rest of the network.Optical isolation protects your devices from transient surges and ground loops on your data line. As a repeater, it extends the distance of an existing RS485 network an additional 1.2 km (4000 ft). Data signals and the power inputs connect to the terminal block. The repeater operates on an external 18~36 VDC power supply. The enclosure can be easily mounted on a standard 35mm DIN rail, and also surface mounted.
