Compact module that can learn up to 4 channels of an IR remote control, once an infrared receiver such as the IR38DM or a compatible one (not included) has been fitted. It has 4 buttons (K1, K2, K3, K4) to store the matching channel, status LEDs for power (D1) and channel storage (D2), and a 6-pin connector for power and outputs. Once the channels have been stored, pressing one of the four buttons on an IR remote control (for example code 2846-TELECIR) will light the status LED and switch the matching output from low to high level (+5 Volt)
