Common 1746-NT8 failures

Failure patterns we regularly see on SLC 500 thermocouple input module hardware like the 1746-NT8:

  • Channel drift, offset or a reading railed at full scale after overvoltage on the field loop
  • Calibration lost on one or more channels
  • Output channel stuck at zero or full scale (NO / NIO modules)
  • RTD / thermocouple channels reading wrong from a failed reference or CJC (NR / NT)
  • Noisy readings from a damaged filter section

Repair or replace?

ReplaceReplace the 1746-NT8 when a channel reads open, pegged, or drifting and the loop cannot wait. The SLC 500 thermocouple input module only carries its channel settings, and those download from the project. Stick with the exact 1746-NT8. The suffix sets the 8-channel density, so a near match is a different unit. A replacement 1746-NT8 is sourced on request, so compare its lead time with a repair before deciding.
RepairAnalog cards are worth repairing because the failure is usually one channel's front end or an isolated supply, and the repair includes recalibration of every channel. Choose repair for the 1746-NT8 when replacements are hard to find or the card is one of several the same age. Most 1746-NT8 units reach our bench with one of two symptoms: “Channel drift, offset or a reading railed at full scale” or “Calibration lost on one or more channels”. Already swapped it out? Repairing the failed 1746-NT8 turns it into a tested spare on the shelf for the next failure. Each 1746-NT8 we repair goes back function-tested with a 1-year warranty.
