20 SLC 500™ RTD/Resistance Input Module

Publication 1746-IN007C-EN-P - December 2002

The module accuracy is dependent on the RTD/Resistance type, the excitation

current, and the input filter selection. The following table shows the module

accuracy and temperature drift when the module has been auto-calibrated at the

operating temperature and when the module’s temperature changes but has not

been recalibrated.

Input Type Resistance Range

(0.25 mA

Excitation)

Resistance Range

(1.0 mA Excitation)

Resolution Repeatability

(28 Hz, 50/60 Hz)

Resistance 150Ω 0 to 150Ω 0 to 150Ω 0.01Ω ±0.04Ω

500Ω 0 to 500Ω 0 to 500Ω 0.1Ω ±0.2Ω

1000Ω 0 to 1000Ω 0 to 1000Ω 0.1Ω ±0.2Ω

3000Ω 0 to 3000Ω 0 to 1200Ω 0.1Ω ±0.2Ω
