3.3.1 Voltage - TO - Temperature Conversion The temperature-versus-voltage relationship of a the thermocouple is not linear. You can reference the thermocouple reference tables to get V to T values. Or use temperature conversion equation to get V to T values. Temperature Conversion Equation: T = a0 ...

4 Signal Connection The OME-DB-889D can multiplex up to 16 channel differential inputs. Input channel selection is controlled by a CN3 D4~ D6 digital output by OME-A-82x series multi-function card. 4.1 Floating Signal Connection The OME-DB-889D has only differential input channels, each input channe...

4.4 Open Thermocouple Detection The OME-DB-889D provides open thermocouple detection through a resistor circuitry. These resisters are normally not connected. The user can find on the back of the board has two solder gaps for each input channel. If you short the solder gaps, the open thermocouple de...
