Can we measure 22 Thermocouple & 20 Voltage signals with an USB-2416-4AO and AI-EXP32?

[rakeshaashay]

We would like check the compatibility of USB-2416-4AO and AI-EXP32 Bundle for our following requirement:

Can we configure and acquire following channels simultaneously with a USB-2416-4AO and AI-EXP32

Thermocouple K type : 22 nos.

Voltage : 20 nos.

Hello @rakeshaashay.

A user can attach up to 16 thermocouples on the USB-2416-4AO and the remaining 6 thermocouples on the AI-EXP32; all in differential mode.  That leaves 20 available analog input channels, with single-ended mode connections, on the AI-EXP32 for the remaining voltage signals.

Please note that the analog input channels are multiplexed into the ADC, so the sampling is not simultaneous.

Hello @rakeshaashay.

For 21 thermocouple inputs and 21 voltage inputs, a user can attach up to 16 thermocouples on the USB-2416-4AO and the remaining 5 thermocouples on the AI-EXP32; all in differential mode.  That leaves 22 available analog input channels, with single-ended mode connections, on the AI-EXP32 for the remaining voltage signals.
