4 Channel Remote Control Circuit Diagram. The receiver provides 4 channel momentary outputs. 3 to 5 vdc 5 v 20 ma receiver.
All outputs are ttl level can be interface with other circuits or relay board. The decoder u1 ht 12d receives serial addresses and data from the encoder that are transmitted by the rf wireless transmitter module. But as far as i.
4 channel remote control circuit diagram ic 4017 tsop trik id this idea came when i had to go back and forth to turn on and turn off the fan and i tho.
Rf remote control relay switch. 4 channel latch or momentary on board jumper for selection. Crystal based oscillator for reliability of operation. Pt2262 used as encoder transmitter and pt2272 m4 decoder receiver ics are heart of the project.
