1.1.1 RTD/Resistance Inputs and Ranges

The table below lists the RTD and resistance types and their associated full-scale ranges,
supported by the IR6I module.
Input Range
˚ Celsius
Input Type
Pt 385 -200 to +850
Pt 3916 -200 to +630
10 Cu 426 -100 to +260
100 Ni 618 -100 to +260
120 Ni 672 -80 to +260
604 NiFe 518 -100 to +200
150 ohm 0 to +1500
500 ohm 0 to +500
1000 ohm 0 to +1000
3000 ohm 0 to +3000

1.1.2 Data Formats

The data can be configured on board each module as:
•
Engineering units x 1
•
Engineering units x 10
•
Scaled-for-PID
•
Percent of full-scale
•
Raw/proportional data

1.1.3 Filter Frequencies

The module uses a digital filter that provides high frequency noise rejection for the input
signals. The filter is programmable, allowing you to select from six different filter
frequencies for each channel:
•
4.17 Hz
•
10 Hz
•
16.7 Hz
•
19.6 Hz
•
62 Hz
•
470 Hz
