Page 6: Introducing The Usb-5201
Chapter 1 Introducing the USB-5201 The USB-5201 provides eight differential thermocouple input channels and two integrated cold junction compensation (CJC) sensors. You can take measurements from type J, K, R, S, T, N, E, and B thermocouples. An open thermocouple detection feature lets you detect a broken thermocouple. An on-board microprocessor automatically linearizes the measurement data. -

Calibrating the hardware Factory calibration The Measurement Computing Manufacturing Test department performs the initial factory calibration. Return the device to Measurement Computing Corporation when calibration is required. The recommended calibration interval is one year. Field-calibration The USB-5201 supports field-calibration with InstaCal. Calibrate the device whenever the ambient temperature changes by more than ±10 °C from the last self-calibration. -
Page 10: Chapter 3 Sensor Connections
Chapter 3 Sensor Connections The USB-5201 supports type types J, K, R, S, T, N, E, and B thermocouples. Thermocouple selection The thermocouple type you select depends on your application needs. Review the temperature ranges and accuracies of each type to determine which is best suited for your application. Screw terminal pinout The USB-5201 has four rows of screw terminals –... -
Page 11: Digital I/O
USB-5201 User's Guide Sensor Connections Digital I/O You can connect up to eight digital I/O lines to the screw terminals labeled . Each terminal is DIO0 DIO7 software-configurable for input or output. If a digital bit is set up as an alarm, the bit is configured for output on power-up, and assumes the state defined by the alarm configuration. -
Page 12: Digital I/O Connections
USB-5201 User's Guide Sensor Connections Digital I/O connections You can connect up to eight digital I/O lines to the screw terminals labeled . You can configure DIO0 DIO7 each digital bit for either input or output. All digital I/O lines are pulled up to +5 V with a 47 kΩ resistor (default). -
Page 13: Chapter 4 Functional Details
Chapter 4 Functional Details Thermocouple measurements A thermocouple consists of two dissimilar metals that are joined together at one end. When the junction of the metals is heated or cooled, a voltage is produced that correlates to temperature. The USB-5201 hardware level-shifts the thermocouple’s output voltage into the A/D’s common mode input range by applying +2.5 V to the thermocouple’s low side at the C#L input. -
