The table below lists the RTD and resistance types and their associated full-scale
ranges, supported by the IR6I module.
Table 1-1. RTD/Resistance Input Ranges
Input Range
˚ Celsius
Input Type
Pt 385 -200 to +850 -328 to 1562
Pt 3916 -200 to +630 -328 to 1166
10 Cu 426 -100 to +260 -148 to 500
100 Ni 618 -100 to +260 -148 to 500
120 Ni 672 -80 to +260
604 NiFe 518 -100 to +200 -148 to 392
150 Ω 0 to +1500
500 Ω 0 to +500
1000 Ω 0 to +1000
3000 Ω 0 to +3000
The data can be configured on board each module as:
• Engineering units × 1
• Engineering units × 10
• Scaled-for-PID
• Percent of full scale
• Raw/proportional data
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
