NPN Open Collector Type
When the load voltage and external power supply are the same. This example is when
the values of the rated load voltage and external power supply for driving the internal
circuit are the same. In this set–up, there is only one power supply.

Notes
1) The resistor in the control unit is 2k
W
for X0 through X5, and
1k
W
for X6 through XF.
2) Either positive or negative polarity is possible for the input
voltage supply.
When the load voltage differs from the 24V DC external power supply for the driving the
internal circuit
Other than 24V DC load voltage, 5V DC and 12V DC and other load voltages can be
connected.
