Wiring Note:
⚫
The wiring principle of high-speed digital output OUT (0-7) and low-speed digital
output OUT (10-19, 34, 35) is shown in the figure above. The external signal receiving
end can be an optocoupler or a relay or solenoid valve, all can be connected as long
as the input current does not exceed 300mA.
⚫
For the connection of the public end, please connect the "EGND" port on the power
supply to the negative pole of the DC power supply of the external input device. If the
DC power supply of the external device and the controller power supply are in the
same power supply system, this connection can also be omitted.
⚫
The E24V port is the freewheeling clamp port of this part of the digital output port.
When this port is suspended, each output port will not have the freewheeling function.
It needs to be connected to the positive pole of the load power supply to enable this
function.
⚫
The E5V port is a 5V power output port, which can be used when some loads need to
provide an external 5V power input, the maximum current is 300mA.
