6.4.1.1 ANALOG DIGIN
The analog digital input block allows the analog input terminals to be used as digital
input signals.
Functional Description
The SINUS/ISD inverter has two analog inputs. There is a digital analog input function block for each: ANALOG
DIGIN 1 is associated with the signal on terminal 2, whilst ANALOG DIGIN 2 is associated with the signal on
terminal 4.
The analog digital input function blocks allow the analog terminals to be used as digital inputs where extra digital
inputs are required. The input voltage or current is converted to a TRUE or FALSE digital signal. Generally,
(when INVERT is FALSE), an input greater than the comparison LEVEL
will cause the output VALUE to be
TRUE. Similarly, an input less than the comparison LEVEL will cause the output VALUE to be FALSE.

Parameter Descriptions Parameter Descriptions
INVERT INVERT Range: FALSE / TRUE
When this is TRUE, the VALUE output is inverted.
LEVEL
LEVEL Range: 0.00 to 100.00 %
This is the level used to determine whether the input is high or low. The actual level
also depends on the hardware range selected.
HYSTERISIS
HYSTERISIS Range: 0.00 to 50.00 %
A hysteresis value used to prevent jitter on the input. The actual hysteresis also
depends on the hardware range selected.
VALUE
VALUE Range:FALSE / TRUE
A TRUE or FALSE output depending on the input volts or current.
