12.1 Sink and Source Output (Transistor)
FX3U Series main units and FX2N Series input/output extension units/blocks of transistor sink output type and
of transistor source output type are available.
1. Differences in circuit
• Sink output [-common]
Output to make load current flow into the output (Y) terminal is
called sink output.
• Source output [+common]
Output to make load current flow out of the output (Y) terminal is
called source output.
