5. Working Principle
The GE IS210AEBIH3B / 104W8300P001 digital input module adopts a full closed-loop working mechanism: on-site switch signal access → optoelectrical electrical isolation → hardware debounce filtering → precise level identification → data verification processing → intelligent fault diagnosis → real-time bus upload. It provides accurate, stable and real-time discrete status data for the Mark VIe unit control system.
During unit operation, various passive discrete signals from site such as valve limit switches, auxiliary equipment start-stop contacts, relay feedback contacts, interlock switches and fault alarm contacts are connected to module terminal channels. All incoming signals firstly pass through independent optoelectronic isolation units to achieve complete electrical isolation between field primary loops and system secondary control loops, blocking the influence of high voltage interference, loop crosstalk and induced voltage. Afterwards, dual processing by hardware debounce circuit and software digital filtering is carried out to filter instantaneous jitter, interference pulses and clutter signals on site for signal purification and status stabilization. The module accurately judges the on-off status of switch signals through high-precision level identification circuit. After data verification, anomaly elimination and status calibration by built-in algorithms, authentic and reliable equipment operating discrete data is generated.
The module monitors loop status, signal condition, hardware operation status and bus communication link status of each channel in real time throughout operation. Once channel open circuit, loop abnormality, signal disorder, communication interruption, hardware fault and other faults are detected, intelligent diagnosis and channel isolation protection mechanism will be triggered immediately to block the spread of single-point faults. Meanwhile, fault codes and abnormal information are uploaded to the upper system to trigger corresponding alarm prompts. Verified and optimized valid discrete status data are uploaded to the system main control unit in real time through the dedicated backplane bus, providing core data support for unit start-stop logic, interlock protection, equipment condition monitoring, fault alarm and sequence control, and fully guaranteeing accurate execution of interlock logic, safe and controllable equipment operation and stable and orderly system working conditions of large gas and steam turbine generator sets.
