4.2 Electrical Wiring
4.2.1 Overview
The XP2F integrates several components electrically, and this section is designated to explain how those
electrical connections should be made. The X35 flow calculation model is the connection point for all
other components in the package, so the wiring is explained in terms of the X35.
4.2.2 X35 Power Supply
The X35 has the following power draw requirements:
• 6-24 VDC
•
2.2 watt draw when screen is off
• 3.3 watt draw when screen is on
4.2.3 Analog Inputs
The X35 has 4 analog input channels that can accept a standard 4-20mA signal. The X35 can provide loop
power to the sensor or allow the sensor to be field powered. The wiring terminals used on the X35
determine whether the analog input provides power. To have the X35 provide loop power to the sensor,
see the wiring diagram in
