signal is displayed “mA” in the screen.
Current 4-20mA speed regulation, Pin8 connects to the positive pole of current analog
4-20mA signal. Pin9 connects to the negative pole. Change the current value of the
analog signal and the speed changes linearly. 4mA corresponds to speed 0rpm, 20mA
corresponds to maximum speed.
Note: DO NOT connect the 0-5V/0-10V signal with 4-20mA input terminal. Wrong
connections may cause damage to the device. The external control plugs must be
connected and disconnected in the power-off status to prevent the external control
interface from being burned.

5V.
2)
Connect Power-GND with the negative pole of external connection power
supply 5V.
3)
Start motor, relay pull-in; Motor stops, relay breaks.
