IS230TNAOH2C is a Analog Output Module developed by GE. It is a part of Mark VIe control system. This module translate control commands and digital data from the control system into analog signals that can be utilized by various external devices and systems. The Analog Output Module offers multiple channels, allowing for the generation of multiple analog output signals simultaneously. Each channel is equipped with advanced circuitry to ensure accurate and stable output signals. These outputs can be used for various purposes such as controlling valves, actuators, motors, or other analog devices within the industrial process. One notable feature module is the incorporation of a normally open mechanical relay for each analog output circuit. This relay serves a dual purpose: enabling or disabling the operation of the output and providing a means to isolate a failed output in a Triple Modular Redundancy (TMR) system. In a TMR configuration, where redundancy and fault tolerance are paramount, the mechanical relay plays a crucial role in maintaining system integrity. If a fault or failure occurs in one of the output circuits, the relay associated with that circuit can be de-activated. This de-activation opens the relay, effectively disconnecting the faulty output from the customer load connected to the terminal board. This isolation ensures that the faulty output does not impact the operation of the remaining circuits, allowing them to continue providing accurate and reliable output signals.
What is IS230TNAOH2C?
It is a Analog Output Module developed by GE.
What is the purpose of the mechanical relay in each analog output circuit?
The mechanical relay included in each analog output circuit serves the purpose of enabling or disabling the operation of the output. It provides a means to control the flow of analog signals to external devices or systems.
Why is the inclusion of a mechanical relay significant in TMR systems?
In TMR systems, where redundancy and fault tolerance are crucial, the mechanical relay plays a vital role. If one of the Parallel Analog Interface Cards (PAICs) fails, it is necessary to isolate the failed output to prevent interference with the correct outputs generated by the remaining PAICs.
How does the mechanical relay isolate a failed output in a TMR system?
When a failure occurs in one of the PAICs, the associated mechanical relay is de-activated. This de-activation opens the relay, interrupting the circuit and effectively disconnecting the failed output from the customer load connected to the terminal board. This isolation ensures that the faulty output does not impact the accuracy and reliability of the overall system operation.
