adaptor purchased in the year of 2018.)

PACKAGE INCLUDES...

• 73VR Application Software CD (model: 73VRPAC2)

• Mounting brackets (two)

(/HA: Not included for desktop type)

GENERAL SPECIFICATIONS

Construction: Panel mount type or desktop type

Degree of protection: IP65; applicable to the front panel of

the recorder with single mounting according to the specified

panel cutout (/HA: Desktop type cannot be mounted on a

panel surface)

■ CONNECTION

Ethernet: RJ-45 Modular Jack

Power input, signal input, trigger input, alarm output:

M3 separable screw terminal (torque 0.5 N·m)

Recommended solderless terminal:

Recommended manufacturer: Japan Solderless Terminal

MFG.Co.Ltd, Nichifu Co.,ltd

Screw terminal: Nickel-plated steel (standard) or stainless

steel

■ MATERIALS

Enclosure: Steel

Bezel: Flame-resistant resin (black)

Front filter: Transparent resin

Isolation: Input 1 to input 2 to input 3 to input 4 to input 5 to

input 6 to input 7 to input 8 to input 9 to input 10 to input

11 to input 12 to trigger input to alarm output to power

input to FG to Ethernet

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.
