Description
The National Instruments USB-TC01 Temperature Input Device is designed with a Full-Speed USB interface and is capable of connecting to one thermocouple channel. It features InstantDAQ technology for immediate data viewing and logging, and is compatible with a range of thermocouples including types B, R, S, T, J, K, E, and N. With a 20-bit ADC resolution and an input range of ±73.125 mV, the device offers a maximum sample rate of 4 S/s. The accuracy of this device is impressive, with a typical value at 0.6 °C and a maximum at 1.25 °C, ensuring precise measurements.
Safety features include overvoltage protection that kicks in at 30 V maximum between TC+ and TC-. The device comes with a 2-meter USB cable and does not require an external power source since it is USB powered. In terms of power consumption, it draws 150 mA from USB when operating and only 2.5 mA in suspend mode, making it an energy-efficient solution for temperature monitoring applications.
