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.
■Differences in circuit
Sink output [-common]
Output to make load current flow into the output (Y) terminal is called sink
output.

■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.
