Transistor output
Sink and source output
Sink output and source output products are available for transistor outputs of the CPU module, I/O modules, and terminal
block.

Output terminal
■ External power supply
For driving the load, use a smoothing power supply of 5-30VDC that can output current two or more times the current rating of
the fuse connected to the load circuit.
Sink output [-common] Source output [+common]
Output to make load current flow into the output (Y) terminal is called sink
output. Output to make load current flow out of the output (Y) terminal is called source
output.
