Number of DC Voltage Sensors that one Pace Data Logger can supply power to:
XR5-SE Data Logger: Up to five (5) DC Voltage Sensors
XR440 Data Logger: Up to three (3) DC Voltage Sensors
XR450 Data Logger: Up to four (4) DC Voltage Sensors
Some sensor combinations may reduce the above count, please contact Pace with your requirements to confirm.
If powered from an external 3.3 V to 5 V dc source, any number of Pace DC Voltage Sensors (up to the maximum number of analog channels) may be connected to a Pace Data Logger.
