National Instruments AMUX-64T Analog Multiplexer
Features

• Active Input Overvoltage Protection; ±35V Powered On
• Expandable to 256 Single-Ended/128 Differential Inputs by Cascading Modules
• Open Component Locations for Custom Filter, Attenuation, Current Measurement, or Ground Referencing
• Onboard Sensor for Thermocouple Cold-Junction Compensation
• Multiplexes 64 single/32 Differential Inputs to the E Series Data Acquisition Devices

The National Instruments AMUX-64T is a front-end analog multiplexer that quadruples the number of analog input signals that can be digitized with a NI MIO board (except the AT-MIO-64). For low-cost thermocouple cold junction compensation, it has an integrated circuit temperature sensor that can be connected as a differential input to 2 of the 64 input channels. Up to 4 AMUX-64T boards can be cascaded to increase the number of thermocouple inputs with cold-junction compensation to 248 in single-ended mode or 124 in differential mode. The AMUX-64T has open component positions on all 64 input channels.
