Connecting Wired 4-20mA Sensors

Connecting Wired 4-20mA Sensors

1.Make certain the sensor's wiring is passed through the opening in the mounting plate.

2.Remove the adapter from the correct input connector headers by pulling the adapter up and off of the circuit board header connectors.

3.Strip the ends of each of the sensor's wires as indicated by the gauge on adapter you just removed.

4.Insert the stripped wire ends into screw terminals of the adapter as indicated by your EA800 Wiring Diagram you completed in the preparation phase. Observe proper polarity. See Figure 15.

5.Secure the connections using the setscrews on the adapter. Check the connection by lightly pulling on each connection.

6.After connecting the wire ends to the adapter, align the adapter to the correct header pins as indicated by your EA800 Wiring Diagram, and press the adapter fully onto the header connector pins.
