8 channel Multi-function infrared controller, each channel independently triggered independent delay, do not interfere with each other.
4 kinds of Functional mode: Non-locking (Momentary );Delay(2/10/60/600/3600seconds); Self-locking (Toggle); Inter-locking (Latch), The function mode and delay time are selected by the Solder pad.
Low pulse trigger(Connect to the power supply GND via the trigger button or low level control via the MCU IO port)
NO : Relay normally open contact
COM : Relay common contact
NC : Relay normally closed contact
Relay open: COM connect NO.
Relay close: COM disconnect NO.
Momentary : Press the remote control button (or trigger input port), Relay open, return to Close after 0.5 second;
Self-locking : Press the remote control button (or trigger input port), Relay open, Press again, port Relay close, and so on;
Latched : Enter the Channel 1 Latched command, port 1 Relay open, port 2-8 Relay close. Enter the Channel 2 Latched command , port 2 Relay open, port 1/3-8 Relay close
Delay : Enter the Delay command, Relay open, delay of 2/10/60/600/3600 seconds)after, Relay close;
Function mode selection by shorting three pads M2 1 0
