“Function Q
2
/Q
a
” output function
Output 1 of DT50-2 Pro is used exclusively for switching (
). Accordingly, the output function cannot be freely selected. You
can choose from the following functions for output 2.
•
4 - 20 mA
•
0 - 10 V
•
Switching
•
“Q
2
=Q
1
not”
•
“OFF” (only in the “Advanced” user level)
These are described in detail in the following.
6.4.2.1
4-20 mA output function
If the 4-20 mA setting is selected, output 2 functions as an analog current output.
The measured value of the sensor is output as a proportional-linear current value that
corresponds to the other sensor settings.
6.4.2.2
0-10 V output function
If the 0-10 V setting is selected, output 2 functions as an analog voltage output. The
measured value of the sensor is output as a proportional-linear voltage value that
corresponds to the other sensor settings.
6.4.2.3
“Switching” output function
Output 2 functions as a switching output for the “switching” output function. Since
output 1 is used exclusively for switching, this setting corresponds to the behavior of
output 1. A switching signal that corresponds to the other sensor settings (
) is output based on the current measured
value.
6.4.2.4
“Q
2
=Q
1
not” output function
In the “Q
2
= Q
1
not”=Q
1
the opposite switching signal to that of output 1 is output via
output 2. For example, if a “high” signal is output at output 1, then the signal output via
output 2 will be “low”. This is also known as a complementary output. This is used if an
error notification is needed in the event of cable breakage.
