Providing Line Termination on the Drop Cable
Overview Drop cables running to J890/J892-00x drop adapters or 410 and 3240 Motion
modules require Modicon 60-0513-000 In-line BNC Terminators that allow you to
disconnect and reconnect the cable.
Installing a BNC
In-line
Terminator on a
Drop Cable
Attach a 90° BNC angle connector to the RIO port on the drop adapter, then connect
the 60-0513-000 BNC In-line Terminator. Connect the BNC connector on the drop
cable to the in-line terminator.
Note: The cables should be labeled at every connection to identify each drop and
trunk cable segment. All taps should be labeled with a number that corresponds to
the drop number specified in the PLC’s I/O Map. Instructional labeling at all in-line
termination points on the drop cable promotes proper cable connection and
disconnect practices.
Note: The 90° BNC angle connector is not available from Modicon. See RIO Cable
Material Suppliers, p. 143 for a list of suppliers.
