It is generally necessary to use as short as possible shielded cable, less than 20m
C. Digital output terminals
When the digital output terminals need to drive the relay, the absorb diode should be
installed on both sides of the relay’s coil. Otherwise to cause damage of the DC 24V
power.
☞Note: The polarity of the absorb diode must be installed properly, shown in fig.3-7.
Otherwise, when the digital output terminal has output signal, immediately the 24V DC
power supply will burn out.
