Chapter 4 : 4-20 mA Signal Configuration / Operation Connecting 4-20 mA Outputs to a SCADA Data Collection
Connecting 4-20 mA Outputs 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 4-Channel particle sensor to the SCADA system's 4-20 mA input. The
cable must be compatible with the 12-pin Molex Micro Fit 3.0 connector plug located
on the rear of the sensor. The following pins are used on the connector.

Table 4-6 Airnet II 4-Channel particle sensor 4-20 mA connector pins

Pin Function
6 24 VDC
5 Current output for Status
4 Current output for Channel 4
3 Current output for Channel 3
2 Current output for Channel 2
1 Current output for Channel 1
12 Ground (24 VDC return)
11 Ground (status return)
10 Ground (Channel 4 return)
9 Ground (Channel 3 return)
8 Ground (Channel 2 return)
7 Ground (Channel 1 return)
1. After completing the cabling for the 12-pin Molex Micro Fit connector, install the
ferrite as close as practical to the connector (that will still allow you to insert
and/or remove the connector in the future).
2. Connect the cable from the Airnet II 4-Channel particle sensor's 4-20 mA output
to the data collection system's input.
3. Set up the data collection system to correctly interpret the sensor's 4-20 mA
output.
