The following diagram shows the dimensions for the CQM1-DRT21 I/O Link
Unit. Refer to the PLC's Installation Guide for the dimensions of the Unit when
it is mounted to the Backplane. (All dimensions are in mm.)
The CQM1 I/O Link Unit is assembled with the rest of the Units in the CQM1
PLC for use as one assembled PLC. The CQM1 I/O Link Unit is connected to
the PLC just like any other PLC Unit. Refer to the operation manual for the
PLC for details.
Note No internal power, I/O power, or I/O wiring is required for the CQM1 I/O Link
Unit because it uses internal I/O bits in the CPU Unit to communicate with the
master.
