Application The
ActionI/Q Q436 field configurable, potentiometer input signal conditioner is
useful in transmitting process control setpoints to remote PID controllers or
interfacing position or level sensors to data acquisition and control
systems.
The Q436's high density DIN rail mounting offers an
extremely compact solution for saving valuable panel space.
Configuration A major
advantage of the Q436 is its wide ranging capabilities and ease of
configuration.
For example, in a valve positioning application a
potentiometer is sometimes used as a feedback signal. Quite often a wide open
valve is only a 25% turn of the feedback potentiometer. In this case the Q438
can easily be adjusted with the zero and span to provide a full scale output
signal (e.g. 4-20mA) representing 0-25% or even 50-75% of the potentiometer
input.
Unless otherwise specified, the factory presets the Model
Q436 as follows:
| Input Range: |
0 to 100% |
| Output: |
4 to 20mA |
 |
|
The Q436 is AC powered and will accept any power between 85
and 265VAC. For other output ranges, refer to Tables 1 and 2 to reconfigure
switches SW1 and SW2 for the desired input and output ranges.
 Calibration
- With power disconnected, set the output and input switch
selectors (SW1 and SW2) to the desired ranges (Tables 1 and 2).
- Connect the input to a potentiometer. Connect the output
to the actual device load (or a load approximately equivalent to the actual
device load value) and apply power.
- Set the input potentiometer to the desired minimum and
adjust the zero potentiometer for the desired minimum output.
- Set the input potentiometer to the desired maximum and
adjust the span potentiometer for the desired maximum output.
- 5. Repeat steps 3 and 4, if necessary, for best
accuracy.
