NI-AMux64T Analog Signal Conditioning Accessories
Used:
• 64-channel multiplexer
• mV, V, current, and thermocouple inputs
AMUX-64T
Analog Input
The AMUX-64T contains 16 CMOS 4 x 1 analog input multiplexers. The
analog inputs can operate as 64 single-ended or 32 differential inputs.
Channel Expandability
You can use one AMUX-64T for 64 input channels. You can also
connect up to four devices together to provide up to 256 channels.
With a single AMUX-64T, four analog input channels are multiplexed to
each multifunction DAQ device analog input. With 4-device operation,
16 analog input channels (four from each AMUX-64T) are multiplexed
to a single DAQ analog input.
Thermocouple Measurements and
Cold-Junction Compensation
A movable jumper connects the temperature sensor of the AMUX-64T
to analog input channel 0. An AMUX-64T configured with the
temperature sensor connected has channels available for reading the
temperature from 60 thermocouples in single-ended mode or
30 thermocouples in differential mode. You can cascade up to four
AMUX-64T devices to increase the number of inputs to 240 in singleended mode or 120 in differential mode. Note: National Instruments recommends 16-bit DAQ devices for measuring thermocouples with the AMUX-64T.
