The Threshold Switch analyzes an analog input value using two threshold values, and switches a digital output accordingly.
The two threshold values form a hysteresis, which prevents frequent toggling of the output when the analog value fluctuates around a threshold value.
Typical applications of the function block are fill level control, heating, ventilation and air conditioning technology, etc.

Von above Voff: The output (O) is activated as soon as the value of the input (V) exceeds the threshold (Von) and deactivated when (V) falls below the threshold (Voff):
Von below Voff: The output (O) is deactivated as soon as the value of the input (V) exceeds the threshold (Voff) and activated when (V) falls below the threshold (Von):
