FP0 Hardware 3.3 Internal Circuit Diagram
3-9Matsushita Electric Works (Europe) AG
When the load voltage differs from the 24V DC external power supply for driving
the internal circuit
Other than 24V DC load voltage, 5V DC and 12V DC and other load voltages can be
connected.

Notes
Either positive or negative polarity is possible for the input
voltage supply.
The I/O number given above is the I/O number when the
expansion I/O unit is installed as the first expansion unit
(see page 7 - 4).
