PCI 4351 cjc with SCB-68

[Craig_APG]

Is it possible to enable cold junction compensation using a PCI 4351 board with a SCB-68 terminal block?

I have searched around and tentatively concluded that it is not possible.  Under the "accessory" option in MAX SCB-68 is not an option, and TBX-68 does not have a checkbox for temperature compensation.

Hello Craig,


National Instruments recommends the following accessories that are designed to be used with the NI 435x for thermocouples/CJC: the cold-junction sensor is on analog channel 0 on the TC-2190, TBX-68T, and CB-68T accessories. Additionally, the NI TBX-68T (used with NI 435x devices only) is the correct acccesory which includes a built-in cold-junction compensation sensor and autozeroing circuitry (compared to TBX-68).


Best regards,
