RS485 communication levels can physically support 32 nodes up-to a maximum distance of 1200 mtrs. CNV-03-B is a RS422 / RS485 repeater. CNV-03-B unit is used where more than 32 nodes are to be connected in the RS485 network or the distance between two nodes is more than 1200 mtrs. It increases number of nodes connected in RS485 network. One CNV-03-B can increase maximum 32 nodes in the network. Multiple CNV-03-B units can be used to support maximum 255 nodes in one network.

CNV-03-B has 2 communication ports. Both the communication ports are screw type easy to use connectors. Communication ports as well as power port are isolated. CNV-03-B supports both 2 wire / 4 wire RS485 and RS422 configuration. It has switch settings to select 2 wire / 4 wire communication on each COM port.w

CNV-03-B operates on 24 VDC external supply.
