7.13. Analog IN
Target application:
The analog input can be used for the dimming by voltage externally put on. The input dims several monitors together.
Alternatively also an external potentiometer (approx. 10kohm 100kohm –) can be attached as voltage dividers.
Function:
If the analog input is evaluated by the controller than is 10V for the full brightness and 0V completely darkly.
Plug:
3 pol Phoenix plug with “screw safety lock” RM3,81 for lines to 1,5mm²
Connection:
Pin Function Description
1 AVOUT Analog Output voltage
2 AIN Analog In
3 AGND Analog GND
Connection data:
AVOUT constantly 10V DC (max. 10mA) against AGND
AIN 0V – 10V against AGND
7.14. Digital IN
Target application:
The input are to be control the Buzzer or the digital outputs. They can be also used to activate features e.g. the analog
similar dimming. It is also conceivable that thereby for different brightness ranges (Day, Dusk, Night) a certain dim
value is activated. The exact function must be programmed into the firmware.
Function:
The contact „digitally in 1 - 3“ is evaluated by the Controller. They can be linked with the outputs „digitally Out“ or their
condition over the serial or LAN interface are sent.
Plug:
4 pol Phoenix plug with “screw safety lock” RM3,81 for lines to 1,5mm²
Connection:
Pin Function Description
1 In 1 Digital In 1
2 In 2 Digital In 2
3 In 3 Digital In 3
4 GND External GND
Connection data:
+24V DC against „external GND“. Galvanical separated.
