Datec photo amplifier

Datec photo amplifier controlls the amplification level for sender and receiver photo cells. 

The relay and the transistor will activate, when sender and receiver are able to see each other, and deactivate when the infrared light is blocked. If pin 8 and 11 is interconnected, this function will be inverted.  

The amplification for each channal is adjusted at 2 potmeters. 

Default settings for "light" or "dark" is chosen with 2 switches. 

The adjustment of the reaction time for the relay and transistor output is fixed at 60msec. and 30 msec. 

Datec DA200 photo amplifier can be connected to 2 photo sources, which can be controlled independently.
