MODEL: 73VR21
81.29920.TB37C (1 GB)
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.
(AP-CFxxxxE3ER-ETNDNR, AP-CFxxxxE3ER-ETNDNRK ...
discontinued)
• SD Card (Compatible with 73VR21 Ver.5.03.xx or later)
Manufacturer: Hagiwara Solutions
Cold junction compensation (CJC) for T/C input: CJC can be
enabled or disabled per each channel.
Model No.: NSD6-004GH (B21SEI
(NSDA-004GT, NSDA-004GL ... discontinued)
SD/CF Conversion Adapter is required to use SD card. There
are some restrictions on using SD cards. For details, refer to
the instruction manual.
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
• SD/CF Conversion Adapter (operation confirmed):
DeLOCK adaptor CF II to SDHC,SDXC
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).
Model: 61796 (operation has been confirmed with the
adaptor purchased in the year of 2016.)
62637 (operation has been confirmed with the
adaptor purchased in the year of 2018.)
PACKAGE INCLUDES...
• 73VR Application Software CD (model: 73VRPAC2)
With Fast setting, sampling time (speed) can be high
through data fluctuations increase.
• Mounting brackets (two)

INPUT SPECIFICATIONS
■ DC Voltage
Input resistance: 900 kΩ min.
Burnout for T/C and RTD input: Upscale, Downscale or No
burnout selectable
Excluding the case in which, with range setting other than
±12 V, ±6 V or ±3 V, a voltage exceeding ±1.3 V is applied.
Input range: ±60 mV, ±125 mV, ±250 mV, ±500 mV,
±1000 mV, ±3 V, ±6 V, ±12 V
Select ‘No Burnout’ to minimize the measuring errors
caused by the sensor/wire resistance and the burnout
sensing current.
