Functional Description

IC3600QOXA2-REV-J is an Overspeed Sensor Card developed by GE. It is a part of Mark I and II control system. It is an essential component for monitoring turbine speed and protecting equipment by ensuring turbines do not exceed safe operating limits.

Components

• Transformer: Located on the left edge of the board, the transformer is labeled with part number 68A993083G1. This transformer plays a crucial role in managing the voltage levels and power requirements of the card, helping to ensure stable operation and protection from electrical surges.
• Relays: Includes two important relay components, each identified with unique part numbers CR120G40A06FB, 68A997168A03. These relays are crucial for controlling circuit pathways within the overspeed sensor system. The 68A997168A03 relay operates at 28 VDC and is critical for triggering actions such as signaling alarms or activating turbine shutdown mechanisms if an overspeed condition is detected.
• Inductors: The board is equipped with inductors labeled 2213PA760387, which serve to manage current and filter signals on the card. Inductors are essential in this type of control equipment to maintain signal clarity and prevent noise from interfering with overspeed detection.
• RESET Button: The RESET button provides operators a straightforward way to clear alarms or reset the overspeed sensor once the turbine is back within safe operational parameters. This manual reset capability is especially useful in early control systems like the Mark I and II, which require physical resets after alarms are triggered.

Features

• Monitoring turbine speed and detecting any conditions that might lead to overspeed. If an overspeed condition occurs, the card uses its relay components to initiate protective actions, such as shutting down the turbine or sounding alarms, thereby preventing potential damage or catastrophic failure.
• Mark I and Mark II systems were among the first to automate and monitor turbine safety, making them pivotal in advancing turbine control. Although the Mark I and II systems are now considered obsolete, the QOXA continues to be used in many facilities that maintain these systems, thanks to its dependable design and safety features.
