Hello Everyone, Has anyone work with the Allen-Bradley Micro830 controller and 2080-RTD2 plugin module? I can't seem to find anywhere in the documentation what the scaling range (data counts) is for the 2080-RTD2 plugin module. If anyone can help it would be greatly appreciated. Thanks |

Hi there, Check out this document: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/2080-um002_-en-e.pdf Go to page 49 for the Non-isolated Thermocouple and RTD Plug-in Modules section. Count conversion information can be found on pg. 54. Good luck! Temperature Conversion – Data to Degree Celsius (°C) The following formula shows how to derive temperature Celsius degree from temperature data word: Temp (°C) = (Data - 2700)/10; These sample equations show how temperature is derived by applying the formula above: 1234 → (1234 - 2700)/10 → -146.6 °C 8000 → (8000 - 2700)/10 → 530.0°C An example to illustrate how overrange and underrange errors are flagged is as follows: A type J thermocouple with temperature data above 1200 °C (14700 counts) flags an overrange error in CCW global variable Px_AI_02/04. The same Type J Thermocouple with temperature data below -210 °C (600 counts) will flag an underrange error in the same CCW global variable. |
