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.
