Connecting to a rotary encoder
When the module is used with an external 5-V power supply, a current limiting resistor
do not have to be inserted. When it is used with an external 12-V power supply,
however, a resistor of about 400 ohms is required.
Figure 3.5.
Connecting to count-match output
The count-match output section has an open collector configuration based on
Optocoupler isolation. Driving the output of this product requires an external power
supply 5 – 12V.
Nominal output: 35VDC 50mA(Max.)

Point
A surge voltage protection circuit is not provided on the output transistors for this
product. Therefore, when driving relays, lamps, and other induction loads using this
product, a surge voltage countermeasure should be provided on the load side. For
a description of how to deal with surge voltages, see "Surge Voltage
Countermeasures".
