Analog as binary or tristate inputs
Analog inputs can be used also as binary or tri-state, i.e. for contact sensors without or with circuit check. The
threshold level is 750 Ω. In the case of tri-state, values lower than 10 Ω and values over 2400 Ω are evaluated
as sensor failure (short or open circuit).

Note:
The name, sensor characteristic and alarm types for each analog input have to be assigned during
configuration.
Note:
Tristate and binary sensors are not suitable for Analog Switch functions.
Analog Voltage sensor
Controller is equipped with +5 V terminal which can be used as power supply for a voltage analog sensor.
