C. Y1 digital output terminal:
When the digital output terminal needs to drive the relay, an absorption diode should
be installed on both sides of the relay coil, and the driving capacity is not more than
50mA. Otherwise, it is easy to cause damage to the DC 24V power supply.
Note: The polarity of the absorption diode must be installed correctly, as shown in
Figure 3-15, otherwise when the digital output terminal has output, the DC 24V power
supply will be burned out immediately.
