Backplane Interconnect
The backplane interconnect is used when connecting Adapter and IO products on a DIN
rail. The interconnect fits inside the channel of the DIN rail and provides for connection of
power and communication to Adapter and IO products.
Table 54: Backplane Interconnect
Table 55: Device/Backplane Interconnect
Short Run Interconnect
To connect the Modbus Adapter to devices without using a backplane, use the RJ style
connectors that are located at the bottom of the D85 IO module. There are two
connections located next to each other that are in parallel with each other, this allows
daisy chaining using Pre-Manufactured cables. There are standard sizes for the Pre-
Manufactured cables. These sizes are listed in the “Renewal Parts” portion of
“Troubleshooting and Maintenance.”
When making this interconnect, refer to the QCPort
System Install and User Manual
(Publication MN05001002E for the recommended cable and connections.
