3.3 Specifications of input/output signals with PLC CPU 
3.3.1 List of input/output signals with PLC CPU 
The QD75MH uses 32 input points and 32 output points for exchanging data with the 
PLC CPU. 
The input/output signals when the QD75MH is mounted in slot No. 0 of the main base 
unit are shown below. 
Device X refers to the signals input from the QD75MH to the PLC CPU, and device Y 
refers to the signals output from the PLC CPU to the QD75MH.
