The Inverter has five digital inputs. There is a DIGITAL INPUT function block associated with
each of these:
DIGITAL INPUT 1 is associated with terminal 20
DIGITAL INPUT 2 is associated with terminal 21
DIGITAL INPUT 3 is associated with terminal 22
DIGITAL INPUT 4 is associated with terminal 23
DIGITAL INPUT 5 is associated with terminal 24
DIGITAL INPUT 6 is associated with terminal 25
DIGITAL INPUT 7 is associated with terminal 26
DIGITAL INPUT 8 is associated with terminal 27
The input electronics of the Inverter converts the input signal to a TRUE or FALSE logic value.
The digital input block takes this value and optionally inverts it before providing the VALUE
output.
