Temperature accuracy for inputs from 4-wire RTDs over temperature span (2.3, 4, and 4.7 Hz filters). This data does do not include the RTD sensor accuracy, which must be included when determining the overall system performance.

 

Three-wire RTDs have similar accuracies, but depend on the lead resistances being balanced.

 

For 2-wire RTDs, the lead resistance of the RTD contributes to the temperature error.

All tolerances double when 24Hz or 28Hz filters are used.

Customer Questions and Answers


  • Question:  What is an IC695ALG508?  Answer:  The IC695ALG508 is an 8-Channel, Isolated, Resistance Temperature Detector Input module from the GE Fanuc RX3i Series.
  • Question:  What does IC695ALG508 do?   Answer:  This module provides 8, isolated differential RTD input channels. 
  • Question:  The configuration for each channel can be what?   Answer:
    • RTD Inputs:
      • 50, 100, 200, 500, and 1000 ohm Pt 385
      • 50, 100, 200, 500, and 1000 ohm Pt 391.6
      • 100, 200, 500, and 1000 ohm Ni 618
      • 120 ohm Ni 672
      • 604 ohm NiFe 518
      • 10, 50, and 100 ohm Cu 426
    • Resistance Inputs:
      • 250, 500, 1000, 2000, 3000, and 4000 Ohms
  • Question:  What is one thing you will need to test IC695ALG508?   Answer:  You will need a high-density terminal strip (IC694TBB032). 
  • Question:  What do I need to know about the high-density terminal strip?   Answer:  You should make sure the lever on it is in the upright-most position, which will turn the LED green to let you know you are fully connected. If it is red or you don't have a light, then you know something is wrong. 
  • Question:  What am I expecting to see when I probe each channel with the resistor?   Answer:  You should expect to see the same number because you should have set them all up with the same configuration. 
  • Question:  Why is this important?   Answer:  It is important because if there is an issue with a channel not reading the same number, then you will know and be able to check into that channel. 
  • Question: What should I do if my IC695ALG508 is not working properly?   Answer:  Your IC695ALG508 may need repair
