6.8 Single-Ended Input Channels
Single-ended channels are designed to measure voltages with reference to the system ground and can
accommodate many analog sensors types including accelerometers, pressure transducers,
geophones, temperature sensors, inclinometers, and more. These channels can also be used to
measure reference voltages.
Sensors that operate on 4.096 V dc can be powered with the node excitation voltage. Alternately,
sensors can be powered with an external source.
The sensor output signal is processed in the node by an 18 -bit analog to digital (A/D) converter, over
the -10.24 to +10.24 V dc range. The resolution of the sensor measurement is dependent on the full
scale output range of the sensor. More resolution can be achieved by changing the single- ended
channel input range, see below.
