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 34 Output Specifications.
For output specifications of the I/O modules, refer to Page 162 Output specifications.
For output specifications of the terminal modules, refer to Page 180 Output specifications.
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
For the CPU module, output module (extension connector type), and input/output module (extension connector type), the
transistor output type is a 8-point common output type.
• 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.
