3.3 Internal Circuit Diagram
When the load voltage differs from the 24 V DC external power supply for the
driving the internal circuit
Other than 24 V DC load voltage, 5 V DC and 12 V DC and other load voltages can be
connected.

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
(*section 5.3).
