6-3. External I/O (Source type (ISC) option)
The source type external input/output signal is an option which can be changed external input/
output signal of F372A to source type. (The standard is sink type.)
The connection of external input/output signal is the minus common.
How to connect external output（Source type）

Minus common connection
A1，A7
A2 ～ A6
A8 ～ A10
DC24V
COM
Output
Ic= app.5mA

DC24V
CAUTION
・Connect elements that can pass Ic=5mA or more.
・The leak current of the elements connected should be 400μA or less.
・External power supply (DC24V) is needed since F372A does not have
the power supply
