4.7 Reference switch inputs
There are 2 reference/stop switch inputs (STOPL / STOPR). Both inputs offer an internal pull-up resistor (1k)
and accept voltages between 0 and +5V.

4.8 General purpose inputs
There are 2 general purpose inputs (IN_0 / IN_1). Both inputs offer internal voltage divider and voltage
limiter and accept input voltages between 0 and +24V. The voltage divider resistors act as pull-down
resistors, also. Both inputs accept digital and analogue signals (depending on software configuration).
