The 2001-TCSCAN is a New switch card from Keithley.
Additional Features:
Nine analog input channels
Scan up to 43 channels per second
Built-in temperature reference for thermocouple cold-junction compensation
Can also measure temperature directly using 2- or 4-wire RTDs (except with Model 2000)
Built-in temperature reference for thermocouple cold-junction compensation
Suitable for general-purpose measurements of voltage, resistance, and frequency
500nV–125V signal range
General: 9 channels of 2-pole analog input, 1 cold junction sensor
Functions: DCV, ACV, 4-wire Ω, Thermocouple, 2-wire Ω, 4-wire RTD, 2-wire RTD, Frequency (can be mixed from channel to channel)
Thermocouple Scan Speed: 25 channels/second @ 0.1°C resolution; 43 channels/second @ 1°C resolution.
Capabilities: Multiplex one of nine 2-pole or one of four 4-pole analog signals into Model 2001 DMM and/or any combination of 2- or 4-pole analog signals
Reference Output:+200µV/°C (+54.63mV at 0°C)
All Inputs Maximum Signal Levels: DC: 110V DC, <1A switched, 30VA maximum (resistive load); AC: 125V AC rms or 175V AC peak, 1A switched, 62.5VA maximum (resistive load)
Contact Life: >105 operations at maximum signal level; >108 operations cold switching
Contact Resistance: <1Ω at end of contact life
Actuation Time: 2.5ms maximum on/off
Contact Potential: <±500nV typical per contact, 1µV max.
Connector Type: Screw terminal, #22 AWG wire size (0.062 O.D.)
Isolation Between Any Two Terminals: >109Ω, <75pF.
Common Mode Voltage: 350V peak between any terminal and earth.
Maximum Voltage Between Any Two Terminals: 110V DC, 125V AC rms.
Dimensions: 21mm high × 72mm wide × 221mm deep (0.83 in × 2.83 in × 8.7 in)
When installed in a 2000, 2001, 2002, or 2010 DMM, the Model 2001-TCSCAN provides up to nine channels of cold-junction compensated temperature measurements and/or voltage, resistance, and frequency measurements. When the card is installed in the 2001 or 2002, the DMM will linearize type J, K, E, R, S, B, and T thermocouples automatically. The Model 2000 DMM provides built-in support for J, K, and T-type thermocouples. The Model 2010 has built-in support for J, K, T, and N thermocouples. Readings are output directly in the user’s choice of Celsius, Fahrenheit, or Kelvin scales. Total system accuracy is 0.65°C (with Type J TCs). When used with the 2001, 2002, or 2010, the 2001-TCSCAN can also measure temperature directly using 2- or 4-wire RTDs.
