IS200DTCCH1A

IS200DTCCH1A is a contact output module developed by General Electric as part of the GE Mark VIe system. It provides a means of converting electrical signals from the Mark VIe system into physical contact closures or outputs. These contact closures can be used to energize or de-energize external devices, such as motors, valves, relays, or alarms, allowing for precise control and coordination of critical operations.

Fault Detection Mechanism

• Redundancy and Fault Detection: Redundant systems alone do not guarantee higher reliability. Fault detection is crucial to ensure components are operating correctly and to allow for timely repairs before a forced outage occurs.
• Methods of Fault Detection:
  • Operator Inspection: Visual and physical inspection of processes and equipment by trained operators to identify abnormalities or damage.
  • Special Hardware Circuits: Dedicated circuits monitor critical components or subsystems for anomalies.
  • Hardware and Software Watchdogs: Watchdog circuits or software modules monitor tasks and processes, triggering actions if failures are detected.
  • Software Logic: Intelligent algorithms detect abnormal conditions or inconsistencies in data.
  • Software Heartbeats: Regular exchange of heartbeat signals between software components to detect failures.
• Comprehensive Fault Detection: Incorporating multiple detection mechanisms and redundant components, such as triple redundant controllers and I/O modules, enhances system reliability and minimizes downtime.

System Output Processing

• Output Processing: Data is transmitted to external hardware interfaces and actuators. In a Triple Modular Redundancy (TMR) system, outputs undergo a voting procedure to ensure redundancy and fault tolerance.
• Triple Modular Redundancy (TMR): Three independent outputs from separate controllers are combined using a voting mechanism to produce a single, reliable output value. This approach ensures system robustness and responsiveness even with potential hardware failures.
• Voting Mechanism: Adapts to different signal types, providing flexibility and efficiency in processing diverse signal characteristics.
