IO171: 16 channel thermocouple & strain I/O module

16 channel thermocouple, resistive sensors and strain gauge measurement module

This I/O module offers versatile support for measuring temperature and strain gauge sensors:


  • The following thermocouple types can be measured: B, S, R, T, E, N, J and K
  • Cold junction compensation is performed inside a dedicated terminal box
  • Thermocouple conversion time is 22 ms

Resistance temperature detectors (RTD)

  • The following types can be measured: NI1000, NI500, NI100, PT1000, PT500 and PT100
  • RTD measurements are ratiometric, using an onboard high precision reference resistor
  • RTD conversion time is 22 ms

Strain gauges

  • All strain gauge types are supported.
  • Quarter, half or full bridge circuit configurations may be used (not included)
  • Strain gauge conversion time is 75 ms

Supported thermocouple types B, S, R, T, E, N, J and K
Supported resistive sensors (RTDs) NI1000, NI500, NI100, PT1000, PT500 and PT100
Supported strain gauges Quarter, half and full bridge
(bridges must be completed outside of the I/O module)
Mean time between failures (MTBF)* 464,000 hours
MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2; Environment: GB 20°C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
