Overview
Remote Control Unit is a combination of infrared hand held transmitter and infrared receiver unit which contains 8 relays that can be controlled by wireless. This makes the unit very easy to operate and integrate with existing systems. Keys 1 to 8 on the remote control operate the corresponding relay on the receiver board, ie. button 1 operates relay 1, button 2 operates relay 2, etc. Relay contact can control any equipment in momentary mode (On till key pressed) or Latch Mode (Toggle on each key press). Each relay has indicator LED showing current status. The transmitter uses a modulated 40 kHz carrier to transmit data about which button is pressed. This method is used in all IR remote controls as it offers a high degree of noise immunity against interfering light sources. At the receiver end the IR receiver module extracts the data signal from the carrier. Receiver Chip decodes this signal and sets the corresponding output high. This active HIGH output is used to operate a relay via ULN2803 which is an octal transistor array.

Features:
8 channels, each individually controlled.Infrared operated from commercial hand-held infrared remote.Long range (>15m) operation.Relay output.
