General Electric IC200MDL650 Input Module

All Mark VIe control systems benefit from the fault detection design of the I/O packs. Every pack includes function-specific fault detection methods attempting to confirm correct operation. This is made possible by the powerful local processing that is present in each input and output pack. Some examples of this include:

•Analog to digital (A/D) converters are compared to a reference standard each conversion cycle. If the converted calibration input falls outside of acceptable ranges, the pack declares bad health.

•Analog output 0-20 mA use a small current-sense resistor on the output terminal board. This output is read back through a separate A/D converter and compared to the commanded value. A difference between the commanded and actual value exceeding an acceptable level results in the output being declared in bad health.

•Discrete input opto-isolators are periodically forced to an on condition, then forced off. This is done independently of the actual input and is fast enough not to interfere with the sequence of events (SOE) time capture. If any signal path is stuck and does not respond to the test command, the signal is declared in bad health.
