Due to supply issues, XR5 Series Data Loggers will not be available until late August 2023.

XR5-SE Data Logger

Miniature XR5 Data Logger with 8 analog and 3 pulse inputs, multi-year battery life with any combination of sensors.

The XR5-SE Data Logger simplifies data logging setup and operation.

  • Compatible with over 60 sensors stocked at Pace.
  • Also compatible with many 3rd-party sensors.
  • All Pace sensors require no external power.

The XR5-SE has 8 multi-range analog inputs, 3 pulse/frequency inputs, and millivolt / thermocouple range options.

Features include sensor excitation, average and peak sampling, memory capacity of up to 260,250 readings (-M models) and real time data output.

Logging modes include delayed start, wrap-around, cycle, log on alarm, and log on external trigger.

Battery life is 2 to 4 years for typical applications.

Sensor Excitation

The XR5-SE includes 5.0 Vdc and 2.5 Vdc sensor excitation terminals.

Excitation time is selectable from 30 milliseconds to 10 seconds.

Pulse Inputs

The sensors below connect to one of three (3) pulse inputs

Wind Speed Sensor

Tipping Bucket Rain Gage

Watt Hour Transducer

Additional DC Voltage Ranges

Each analog input can be set to any range below using a Pace Scaling Cable

0 - 10 Vdc +/-2.5 Vdc -7.5 to 12.5 Vdc
0 - 15 Vdc +/-5.0 Vdc -12.5 to 17.5 Vdc
0 - 20 Vdc -2.5 to 7.5 Vdc -27.5 to 32.5 Vdc
0 - 30 Vdc 0 - 60 Vdc -57.6v to 62.6 Vdc


Millivolt / Thermocouple Option

A Millivolt Option adds two millivolt ranges to each analog input, and all XR5-SE features and range selections are retained.

Model Millivolt Range A Millivolt Range B
Range Resolution Range Resolution
XR5-SE-20mV 0-10 mV 2.4 uV 0-20 mV 4.8 uV
XR5-SE-50mV 0-25 mV 6 uV 0-50 mV 12 uV
XR5-SE-100mV 0-50 mV 12 uV 0-100 mV 24 uV
XR5-SE-250mV 0-125 mV 30 uV 0-250 mV 61 uV
XR5-SE-500mV 0-250 mV 61 uV 0-500 mV 122 uV
XR5-SE-1000mV 0-500 mV 122 uV 0-1000 mV 244 uV

The -20mv or -50mv option is recommended for Thermocouple applications.  The -20mv option provides higher thermocouple accuracy.  The -50mv option provides higher temperature ranges for some thermocouples.  See pages 97-101 of the XR5-SE User's Guide for details.  Pace stocks the PT450 Thermocouple Probe for thermocouple applications.

Millivolt option dash number Additional range selections available for each analog channel
-20mV 0-10 mV and 0-20 mV
-50mV 0-25 mV and 0-50 mV
-100mV 0-50 mV and 0-100 mV
-250mV 0-125 mV and 0-250 mV
-500mV 0-250 mV and 0-500 mV
-1000mV 0-500 mV and 0-1000 mV
