Installation and Setup
X-320M™ User's Manual
2.2.4 Frequency Input
Sensors that output a frequency can be connected to the Frequency Input. Connect one end of the
sensor to FreqIn and the other to GND. Figure 2.2.g illustrates a wind speed sensor being connected to
an X-320M™.
Wiring Considerations
The frequency input on X-320M™ is very sensitive and can be affected by low level noise. The Vin- on
X-320M™ should be connected to earth ground. Additionally, all cable shields should be connected to
earth ground. Users should observe single point ground strategies, typical of instrumentation systems.
Proper grounding can be accomplished by connecting the grounding cables to either the AC mains
ground or to the station ground.
