■ Output Connections
Units with Relay Outputs
All four relay output circuits in both CPU Units with 10 I/O points and Expansion I/O Units have independent contacts. CPU Units with 20 I/O points
have 4 independent contacts (Q0 to Q3) and the remaining four (Q4 to Q7) have 2 points/common. There are no restrictions for polarity.
Standard LCD-type CPU Units, LED-type CPU Units, and Economy-type CPU Units
Communications-type CPU Units
Units with Transistor Outputs
For CPU Units with 10 I/O points and Expansion I/O Units, all 4 outputs in the transistor output circuits have independent circuits. The terminals of
output have polarity given on the terminal block, but no problem will result from reversing the connection positions of the power supply and load.
For CPU Units with 20 I/O points, outputs Q0 to Q3 in the transistor output circuits have independent circuits and outputs Q4 to Q7 have 2 points
per common. The terminals of output Q0 to Q3 have polarity given on the terminal block, but no problem will result from reversing the connection
positions of the power supply and load.
Note: Do not exceed a cable length of 10 m when connecting transistor outputs.
