At an OR-gate, the result is '0' if no condition is valid.
Unconnected inputs do not affect the result.
In the right example,
the output will be
active (1)
if:
ingang1 is greater than 100 (e.g. analog input)
OR
Entrance2 is smaller than 200 (e.g. analog input)
OR
Entrance3 is larger than 0 (e.g. digital input)
OR
Entrance4 is smaller than 1 (e.g. digital input)
AND-GATE:
Left stand the 4 entrances, and on the right
the digital output
Each input can be compared to a threshold. This value
can be positive and negative, and one can compare it
to 'larger than' or 'smaller than'.
At an AND-gate, the result is '1' if all conditions are
valid. Unconnected inputs do not affect the result.
In the right example, the output will be active (1)
when:
Entrance1 greater than 100 (e.g. analog input)
AND
Entrance2 is smaller than 200 (e.g. analog input)
AND
Entrance3 is larger than 0 (e.g. digital input)
AND
Entrance4 is smaller than 1 (e.g. digital input)
DIFF-GATE:
This module contains 2 separate logics that allow one
to compare an input value with a starting value and a
stop value (= hysteresis).
On the left are 4 entrances, and on the right there are
2 digital exits. The
RED
numbers show the status of
the entrances and exits (ideal for 'debugging')
On Input1 or Input3 one can connect an analog
measurement (e.g. CO2 measurement)
On Enable1 or Enable2 one can possibly connect a
switch clock. If the Enable is off, output1 or output 2
will always be off, regardless of the conditions.
Unconnected Enable inputs will keep the logic active at
all time.
If the input exceeds the starting value, the output will
become active. If the input is smaller than the stop
value, the output will be switched off.
This allows one to set a condition for, for example, a
fan control, which will switch on or off in function of
the CO2 with the desired hysteresis.
ADD:
add up to 4 analogue values. Links can have up to 4
analog values attached
Be. PLEASE
NOTE: DON'T ADD APPLES WITH PEARS.
In other words, this module can only work correctly if
the inputs have the same units (vb volts, amperen
watt...)
In the right example there are 2 exits available:
