Customers can choose whether to have 433M remote control function according to their actual needs. The remote control distance is about 10m .
3. Mode introduction:
3.1, Self-latching mode :each channel independent control ,press the button to open the channel and it will be close when button be pressed again.
3.2, Inching mode :each channel independent control,press the button to open the channel and it will be automatically close after a delay ,can set inching time 0.5S-3600S.
interlocking mode : all channel are correlative ,only one channel is allowed to open at the same time , all mode can via APP choose by itself .
4 channel outputs are relay switch signals, can be used to control the power supply voltage for DC0-30V/AC0-250V electrical appliances,select the appropriate wiring method for different appliances, make a example for Control light fixture and motor positive and negative rotation as below.
4.1,Control light fixture
4.2, Control DC motor Positive and Negative Reverse
(1) Channel 1 open ,channel 2 close motor M1 Forward (2)Channel 1 close .channel 2 open motor M2 Reverse
