Wiring Section 2-2
(2) Transistor Output Type
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.
Precautions for Correct Use
• Do not exceed a cable length of 10 m when connecting transistor
outputs.
