Digital output connection
All universal output ports are of open-drain output ports, and the drive current
of the output port is within 1.5A (if only one-way output port is used, the drive current
can reach 2A), make sure if the output port drive current meet the requirements when
using. If the current drive capability is insufficient, an external relay can be used for
current expansion, and the follow-current protection diode shall also be connected.
Taking OUT18 as an example. The general electromagnetic relay of output port
drives is connected as below. The polarity of the electromagnetic relay coil is not
required to be considered if special instructions are provided.
