When the digital output terminal needs to drive the relay
,
an absorption diode shall be
installed between two sides of the relay coil
.
Otherwise
,
it may cause damage to the 24
VDC power supply
.
The driving capacity is not more than 50 mA
.
Note
Do not reverse the polarity of the absorption diode during installation
,
as shown in Figure
