GE IS230TICIH3A MKVIe, Isol. Contact Input Assembly, TMR

 

The IS230TICIH3A is used in mission-critical industrial settings where the loss of a digital input signal could lead to a catastrophic event or significant downtime, especially in environments with significant electrical noise or voltage differences.

  • Power Generation: It is a core component in power plants to monitor the status of critical devices on gas and steam turbines, such as valve limit switches and emergency trip buttons. The TMR redundancy ensures that even if a module fails, the control system still receives vital safety data.
  • Oil and Gas: In refineries and offshore platforms, it helps monitor critical discrete signals where continuous operation is essential, such as the open/closed status of emergency shutdown valves or the state of fire and gas detectors.

الوصف

The GE IS230TICIH3A is a triple-modular redundant (TMR) isolated contact input assembly for the GE Mark VIe control system. This module is a complete, pre-configured unit designed for high-reliability applications that require electrical isolation for binary (on/off) signals.

 

Key Features

 

  • Isolated Contact Input: The module’s primary function is to handle binary (on/off) signals while providing electrical isolation. This protects the control system from ground loops, electrical noise, and high voltage spikes from the field devices. The “I” in “TICI” signifies “Isolated.”
  • TMR (Triple-Modular Redundant): This is the most critical feature. The TMR configuration uses three identical I/O packs operating in parallel. The system employs a voting algorithm to compare the inputs from all three packs, ensuring that the control system receives the correct information even if one or two modules fail. This redundancy is the core of its high-reliability design.
  • Assembly: The part number signifies a complete, ready-to-install unit, consisting of both a terminal board and the electronic I/O packs.
  • Mark VIe Integration: As part of the IS230 series, this assembly is designed to seamlessly integrate with the Mark VIe control platform, which is widely used for controlling turbines in power generation and other heavy industries.
