[Caution] When connecting the phototransistor output to the input circuit, be sure to allocate an input current of
approximately 7 mA at 24 VDC. Especially when using a photo diode and a phototransistor (sensor) away
from each other, it is recommended to verify the current that can be carried in the design stage.
The output circuit protective fuses prevent failure in case of load short-circuit and
improper connections.
Please do not connect loads that cause the current to exceed
the maximum rated current. If the maximum
rated current is exceeded, the internal
transistors may be damaged.
