4.21.1 Use analog control inputs
The analog control inputs measure the voltage between GND and DC 10 V.
Fig. 30: Use of analog control inputs
A variable linear resistor 10 k potentiometer with at least 0.05 W (1/20 W) is
required for this function.
The resistor is connected between GND and 10 V. The wiper is connected to an
analog control input.
4.22 Install relay outputs
The PC1001-A2 and PC1002-A2 Novigo Core digital audio matrix boards both
provide 8 connectors ('1-DO' to '8-DO') with 8 relay outputs in the logic out area.
The relay outputs are used to activate LEDs or to communicate a status change of
the system.
The relay contacts can switch a voltage of up to 48 V.
