Burnout for T/C and RTD input: Upscale, Downscale or No
burnout selectable
Select ‘No Burnout’ to minimize the measuring errors
caused by the sensor/wire resistance and the burnout
sensing current.
With RTD input, the signal may go transiently to the
opposite direction from the burnout setting.
With DC input, the burnout setting is ignored and the
burnout sensing current is cancelled.
Cold junction compensation (CJC) for T/C input: CJC can be
enabled or disabled per each channel.
CJC sensor attached to Input 1 and Input 7* terminals.(Input
7 for the 73VR2108, 73VR2110 and 73VR2112)
Operating mode setting: Application software; burnout type,
cold junction compensation, line noise frequency, A/D
conversion mode setting available
Line noise filter: NMNR ratio to the line frequency and its
harmonic contents can be optimized. Factory set to 50/60
Hz mode for use with both frequencies.
Select either frequency for the most effective result.
A/D conversion mode: Fast, Medium or Slow selectable.
With Slow setting, data fluctuations are minimized with
limited sampling time (speed).
With Fast setting, sampling time (speed) can be high
through data fluctuations increase.

directly mounted to the I/O terminals; wire resistance;
burnout sensing current with upscale/downscale settings.
With 100 msec. storing rate, measured value may be susceptible to inaccuracies due to the fast update cycle. If this

Input Connection Examples
Remark 1:
Remark 2:
Remark 3:
Remark 4:
In order to prevent instability in measured values caused by noise entering through the I/O terminals,
grounding the signal shield to a most stable earth point in the environment is recommended.
The smaller is common mode voltage (DC and AC) between C terminals and between C and FG, the better is
measuring accuracy. Connecting between C terminals and if possible to FG will yield the best accuracy.
Resistor modules (model: REM3-250) can be connected to 1A through 12C terminals to convert current inputs
into voltage. However, it is not recommended when TC inputs are mixed because the heat developed on and
around the REM3 affects the cold junction compensation performance. We recommend that REM3 be connected
on a separate terminal board.
When the internal temperature sensors are used for CJC, temperature imbalance around the terminal block affects
greatly the CJC accuracy. In order to minimize such imbalance, do not use wires of large diameter which has large
heat dissipation. Be sure to close the terminal cover. Do not expose the module directly in the line of wind from a
cooling fan.
