Solar Irradiance Sensor with CompactRIO
Hello community,
I am new to NI technologies and I want to use a solar irradiance sensor with the CompactRIO. I do not know how to connect that to an analog module. The picture of the sensor is attached to this post.
Thank you very much!
Based on the datasheet that you didn't provide here (Si-Sensor_2017_E.pdf) I'd guess you have 4 wires.
Two must be connected to a separate power supply. The other two can be measured as a differential analog voltage with signal between 0 and 1.5V, with 1.5V corresponding to 1500W/m^2.
The table on the last page describes which pin is which connection.
What C-Series analogue module are you using?
When wiring the device to the c-series module, make sure the -ve power wire is bridged to the c-series module common (usually the bottom screw terminal on an 8 channel module), and to pin 4 of the sensor. This ensures there's a common voltage reference when reading the irradiance signal.
Along with the irradiance output on pin 2, your sensor also has a temperature output of 0-2V (-40 to +90 degC) on pin 1 which might be useful to hook up.
