DAS-TC Series

Temperature Input

Temperature input functions and methods supported

UL: cbTIn(), cbTInScan()

UL for .NET: TIn(), TInScan()

Temperature input argument values

Options NOFILTER

Scale CELSIUS, FAHRENHEIT, KELVIN

HighChan 0 to 15

Hardware considerations

Pacing input

The rate of measurement is fixed at approximately 25 samples per second.

Selecting thermocouples

J, K, E, T, R, S, N, or B type thermocouples may be selected using InstaCal.

Open thermocouples

When using cbTInScan() or TInScan() with the DAS-TC, an open thermocouple error (OPENCONNECTION) on

any of the channels will cause all data to be returned as –9999.0. This is a hardware limitation. If your

application requires isolating channels with defective thermocouples attached and returning valid data for the

remainder of the channels, use the cbTIn() function or TIn() method instead.

To read the voltage input of the thermocouple, select VOLTS for the Scale parameter in cbTIn() and

cbTInScan(), or TIn() and TInScan().
