11.3 Circuit diagrams
Digital inputs:
The input signal is active when the
optocoupler is switched on
The inputs are activated when the
input pin is short-circuited to the GND
pin
Digital outputs:
If the digital output is set,
the optocoupler is conducting
Foot switch:
The footswitch input signal is activated
when the input pin is short-circuited to
the GND pin
Do NOT apply an external supply
voltage to these pins!
