4.6. Digital Outputs
Figure 4.3 shows an example wiring of the digital outputs. All opto-isolated
digital outputs will be PNP type.
Figure 4.3
The opto-supply must be connected to +12 to +24VDC in order for the digital
outputs to operate.
When activated, the opto-isolator for the digital output pulls the voltage on the
digital output line to the opto-supply. The maximum sink current for digital
outputs is 50mA. Take caution to select the appropriate external resistor so that
the current does not exceed 50mA.
When deactivated, the opto-isolator will break the connection between the digital
output and the power supply.
4.7. Analog Input
Analog inputs are 0 to 3.3V range and 10 bit in resolution. Using the analog
input, analog speed control can be achieved. Section 7.9 will provide details on
analog speed control mode. The maximum source current for the analog input is
10mA. The
recommended potentiometer range is 1KΩ to 10KΩ.
