Relay output Transistor output
Note: 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.
Note: Transistor Output Type
All four transistor 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. The terminals have polarity,
but the power supply and load connections can be swapped
