The
3:0
control block is a pulse spacing modulator with which data values can be digitized
IO-
Modul
) and displayed.
A data value of 0 - 100 available at the input is converted to a frequency (
mit TTL-Pegel
), the
on/off time ratio of which is the percentage equivalent of the data value.
The
IUHTXHQF\
of the output signal is given in the parameter window and can lie in the range of
0.01 to 0.1 Hz.
([DPSOHV
If a data value of
is present at the input then the output value will also be
.
If a data value of
is provided to the input then the output value will be a rectangular pulse
signal with the defaulted
IUHTXHQF\
and an On / Off ratio of 1:3 (
RI WKH 7LPH 2Q
, 75% of
the time off).
If a data value of
is provided to the input then the output value will be a rectangular pulse
signal with the defaulted
IUHTXHQF\
and an On / Off ratio of 1:1 (
RI WKH 7LPH 2Q
, 50% of
the time off).
If a data value of
is provided to the input then the output value will be a rectangular pulse
signal with the defaulted
IUHTXHQF\
and an On / Off ratio of 3:1 (
RI WKH 7LPH 2Q
, 25% of
the time off).
If a data value of
is present at the input then the output value will be
TTL High
.
The
3:0
control block is primarily used in order to control devices via the digital outputs (
IKA
Laboratory Technology IO Module
) such as heating plates, heating mushrooms and others with
the help of the
control block "PID Controller"
.
In this fashion virtually any heating device can be equipped with a modern, precision temperature
control.
Carry out the following instructions:
1. Call up the parameters window by double clicking on the icon.
2. If necessary, enter the
1DPH
of the module into the "Designation" text field.
3. Select
