Transistor output

For output specifications of the CPU module, refer to Page 36 Output Specifications.
For output specifications of the I/O modules, refer to Page 195 Output specifications.
For output specifications of the terminal modules, refer to Page 214 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 cable type), input/output module (extension cable type), powered input/output
module and high-speed pulse input/output module, the transistor output type is a 4-point or 8-point common output type.
• Sink output
Connect each COM (number) terminal to the minus side of
the load power supply.
The COM terminals are not connected internally.
