These inputs are logical low side inputs where:
n The
active level is: tied to GND
n Inactive
level is: open circuit
n The
cleaning contact current is: 10mA at +VBAT=28V
The input status is available for the application with
the mnemonics “Input_Boo”.
The logical thresholds are adjustable by parameter
“high threshold” and
“low threshold”.
See model below.

The area between the two thresholds works as a hysteresis for the input
status. The input status remains active until the level is higher than the
inactive level and the input remains inactive until the level is below the
active level.
The “threshold_fault”
value indicates to the Application that the input is between the two thresholds.
The fault detection is monitored by the Equipment
Variable (more details).
It's possible to apply a filtering on this input.
The filtering gain is adjustable with parameter
“Filtering value”. The
filtering value is ajustable between 5ms to 480ms.
