Output Wiring

The output wiring of the CPU modules, I/O modules, and terminal modules is explained below.

Transistor output

For output specifications of the CPU modules, refer to Page 20 Output Specifications. For
output specifications of the I/O modules, refer to Page 116 Output specifications.
For output specifications of the terminal modules, refer to
Sink and source output
Sink output and source output products are available for transistor outputs of the CPU module, I/O modules, and
terminal modules.
■Differences in circuit
• Sink output [-common]
Output to make load current flow into the output (Y) terminal is
called sink output.

Handling of transistor output
■Output terminal
8 transistor output points are covered by one common terminal.
• Sink output
The COM (number) terminals that are connected each other
inside the PLC are prepared. For external wiring, connect the
COM (number) terminals outside the PLC to reduce the load per
one COM terminal.

■External power supply
For driving the load, use a smoothing power supply of 5 to 30 V DC that can output a current two or more times the
current rating of the fuse connected to the load circuit.
■Insulation of circuit
The internal circuit of the PLC and the output transistor are insulated with a
photocoupler. The common blocks are separated from one another.
■Display of operation
With the DISP switch set to OUT, the LED turns on and the output transistor turns on when photocouplers are actuated.
