143. User’s Manual
Each analog input can be configured according to the sensor working scale (if needed). In the
following example, a temperature sensor was connected to input 2. The main features of the
temperature sensor in the example are:

Output: Linear 0-10 VDC

Working range: -20 to 70 deg
Figure 5. Temp sensor. Temp (Voltage)
In order to configure the MPC-143's channel 2 go to " Analog inputs>configuration ". The steps to
be followed are:
1.-Select the channel range according to the connected sensor output type. In our case, the
temperature sensor is 0-10 VDC sensor.
2.-Select the low conversion point. If you want to acquire the sensor value in voltage, fill with '0'.
In our case, as we want to read directly the temperature value, we fill it with '-20'.
3.-Select the high conversion point. If you want to acquire the sensor value in voltage, fill with
'10'. In our case, as we want to read directly the temperature value, we fill it with '70'.
4.-In order to configure and save the conversion limits click on 'SET'
5.-Click on general 'SET' for configuring also the AIN2 voltage range.
