Signal Connection
Connection to Open Collector Output
To connect with open collector output, an external power supply is necessary.
Some motor drivers also provide the power source. The connection between
PCI-8136M, encoder, and the power supply is shown in the following diagram.
Please note that the external current limit resistor R is necessary to protect
the PCI-8136M input circuit. The following table lists the suggested resistor
value according to the encoder power supply.
