RTD Error
Module error on the 1756-IR6I module is defined in ohms and is calculated across
the entire input range that is selected, not the available range of a sensor used with the module.
For example, if the 1…487 input range is used, the module error is calculated across 507 (actual range = 0.86…507.86 ).
The error in ohms translates to temperature, but that translation varies because the
relationship is non-linear. The most effective way to check a 1756-IR6I module
error is to calculate the error in ohms and use that value in a linearization table to check the temperatureerror.
If the module is calibrated at operating temperature and the operating temperature remains relatively stable,
calibration accuracy is better than 0.1% of the full range for the first year after calibration.
This 0.1% value is a worst case value. In other words, with the 1…487input range that is selected,
the worst case module error is 0.507.

Finally, you must check an RTD linearization table to determine the temperature error
to which an error of 0.507translates. For example, if the 1756-IR6I has a 0.1% (or 0.507 )
error and is operating at 0 °C (32 °F), the temperature error is -1.25…1.2 °C (-2.25…2.16 °F)
when the Platinum 385 sensor type is used. However, this same ohms error,
when calculated in an operating temperature of 200 °C (392 °F), translates to a temperature error of -1.4 °C…1.4 °C (-2.52…2.52 °F).
The strength and versatility of the Universal Remote I/O network comes from the breadth of products it supports.
In addition to 1746 I/O, the Universal Remote I/O network supports many Allen-Bradley and third-party devices.
Typical applications range from simple I/O links with controllers and I/O, to links with a wide variety of other types of devices.
You connect devices through remote I/O adapter modules or built-in remote I/O adapters.
Using the Universal RIO Network instead of direct-wiring a device over a long distance to a local I/O chassis reduces installation,
tart-up, and maintenance costs by placing the I/O closer to the sensors and actuators.
SLC 5/03, 5/04, and 5/05 processors support pass-thru which lets you configure RIO devices remotely from an Ethernet,
DH+, or DH-485/DF1 network, as well as block transfer instructions for faster reading and writing of I/O data.
