With the aid of this circuitry it is made possible to carry out functional tests of infrared remote controls used in TV-sets and video devices, etc. Whenever there is radiation of infrared beams on the Special-Sensor, the LED will light up and indicate that the infrared remote control is operated. As accessories is available our kit B 197 Relay Card . This could be connected with the Infrared Detector and it is then possible to switch through the relay contact loads up to 3 A Operating voltage 9 V/DC( 8 - 12 V/DC) Current consumption without signal < 200 uA Current consumption with a signal of a IR remote control approx. 2 - 15 mA Range between remote control and infrared detector approx. 2 - 10 cm, depending on the remote con
