Light  Control  System

DL 2686

Module DL 2686 represents a process for the control of the light.
In this module an incandescent lamp represents the opto-transmitter element, while a phototransistor is the opt-receiver element.
There are different possibilities for generating noise variables.

Power supply: +15 V ; 0 V ; -15 V
Signal voltage range: 0 ... 20 V
Output signal: 0 .... 10 V
Maximum power: 10 W

Description
1. Terminals for the power supply to the incandescent lamp
2. Terminal fro the output signal from the phototransistor
3. Potentiometer for the manual insertion of the noise variable Z1, operating on the opto-transmitter element
4. Terminal for the insertion of the noise variable Z2, operating on the opto-transmitter element
5. Switch for the selection of the noise signal operating on the opto-transmitter element (Z1 or Z2)
6. Terminal for the insertion of the noise variable Z3, operating on the opto-transmitter element
7. Translucid panel through which it is possible to generate a further noise variable (Z4) on the process, by changing the ambient light
