Connecting to a SCADA Data Collection System
To connect to a SCADA data collection system, build a cable that will allow connection of
the Airnet II particle sensor to the SCADA system’s 4-20 mA input. The cable must be
compatible with the 6-pin Molex Micro Fit 3.0 connector plug located on the rear of the
sensor. The following pins are used on the connector
1.
Connect the cable from the Airnet II particle sensor’s 4-20 mA output to the data
collection system’s input.
2.
Set up the data collection system to correctly interpret the sensor’s 4-20 mA output.
