The board has only one  relay driven by TTL circuit . The board works on 5V but the input signal can come directly from Raspberry Pi and Arduino  output working at 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

The regulated power supply accepts unregulated intputs from 12V to 15V AC or DC and gives regulated output of 3.3V  5V and 12V suitable for  projects which needs precise voltage to work. The input can come from step down transformer. Since board has diode  bridge input polarity does not matter.All outputs are brought to screw terminal. There is also an unregulated output voltage to drive high current loads like relays and motors.

LCD stands for Liquid Crystal Display. LCD is finding wide spread use replacing LEDs (seven segment LEDs or other multi segment LEDs) because of the the ability to display numbers, characters and graphics. This is in contrast to LEDs, which are limited to numbers and a few characters.
