Model 10A10-4
 Quad Isolated Thermocouple Conditioner Card

The Model 10A10-4 is a precision conditioner designed for TC-based temperature measurements requiring high input isolation. It is identical to the Model 10A9-8C, except that
  • it accepts four independent TC signals (rather than eight), and may only be used in System 10
  • its inputs are transformer-isolated, so that sensor-to-chassis and/or sensor-to-sensor common-mode voltages as high as 1500 V-DC can be accommodated at DC or low frequencies without damaging the instrument or perceptibly affecting measurement accuracy (at 60 Hz, the common-mode voltage can be as high as 1000 V-AC (rms))
  • in the event of an "open TC" condition, it will report a negative off-scale reading (only)
Like the Model 10A9-8C, the Model 10A10-4 normally uses an "absolute" calibration procedure. Like the 10A9-8C, it includes a rear-panel connector block with screw terminals for attachment of TC leads (which cannot be soldered), and operates in conjunction with the Model 10A11 Thermocouple Output Processor Card. One Model 10A11 must be installed in every System 10 A-Card rack containing one or more Model 10A10-4's.

Specifications:
  • Measurement Range and Resolution: See Table below; automatically selected- on an individual channel basis- when the channel is configured
  • Linearization: Internal digital look-up table; ±0.05° C
  • Reference-Junction Compensation: At connector block, using built-in precision thermistor, or at remote TC site, using the Model 10CTJB-8 Thermocouple Junction Box
  • Thermocouple Break Detection (per channel): Off-scale negative indication
  • Amplifier (per channel):
      Common-Mode Range: At DC, ±1500 V-DC operating and without instrument damage; at 60 Hz, ±1000 V-AC (rms) without instrument damage
      Common-Mode Rejection Ratio: DC: -154 dB; at 60 Hz: -160 dB
      Input Impedance: Differential: 10 M-ohm; Common-Mode: infinite
      Offset: Initial: ±5 µV; vs. Temperature: ±0.1 µV/°C; vs. Time: ±1 µV/month
      Gain Accuracy: ±0.02% of absolute mV input range of -10 to +80 mV
      Gain Stability: vs. Temperature: ±25 ppm/°C; vs. Time: ±20 ppm/month
  • Filter (per channel): 2-pole modified Butterworth; 3 dB down at 1 Hz; 60 dB down at 60 Hz
      Step-Response Settling Time (Full-Scale Output):
      To 1% of final value: 0.3 sec
      To 0.1% of final value: 0.6 sec
      To 0.02% of final value: 1.5 sec
  • Total System Accuracy (typical, including Model 10A10-4, Model 10A11 Thermocouple Output Processor, and system data collection and processing): see Table below
  • Auxiliary Outputs: None
