Figure 3-1: The Optoisolated Inputs.
Using an Isolated Power Supply
To take full advantage of opto-isolation, an isolated power supply should be used to provide the voltage at the input
common connection. When using an isolated power supply, do not connect the ground of the isolated power to the
ground of the controller. A power supply in the voltage range between 5 to 28 Volts may be applied directly (see
Figure 3-2). For voltages greater than 28 Volts, a resistor, R, is needed in series with the input such that:
1 mA < V supply/(R + 2.2KΩ) < 11 mA
