QCPort Connections
Interconnects/Connections
Connecting the I/O modules together and to other IT. family products involves using one or more of the interconnect connectors. The
I/O product family uses two types of connectors:
• The backplane interconnect
• The short run interconnect
These interconnects provide the I/O module with power and communications.
For more information on making interconnects, the use of interconnects and the restrictions placed upon interconnects, refer to the IT.
QCPort System Install and Planning Guide (Publication No. MN05001002E).
QCPort Backplane Interconnect
The QCPort backplane interconnect is used when connecting the Adapter and I/O modules on a DIN rail. The interconnect fits inside
the channel of the DIN rail and provides for connection to power and communication to the Adapter and I/O products (Figure 31 and
Figure 32).
