IC3600QOXC is a Speed Control Sensor Card developed by GE Fanuc. It is a part of Mark I and Mark II series. This card is designed to monitor and control the speed of turbines within industrial systems, making it a critical component for ensuring turbine performance and safety. With its frequency-based inputs, output signals that trigger under predefined conditions and a latching trip indication system, this card ensures that turbines operate within safe speed limits, helping to protect both the machinery and the broader system from damage.
The QOXC card operates by receiving a frequency signal that is proportional to the speed of the turbine. This input frequency is received between the IN and ACOM pins, allowing the card to monitor the turbine's rotational speed in real-time.
The QOXC card includes a latching circuit that holds the trip indication signal on TPL. This feature ensures that once the turbine speed reaches a predefined threshold, the system will activate a trip signal, preventing the turbine from continuing operation at unsafe speeds. The trip signal can be latched, meaning it will remain active until it is manually reset.
Inhibition of Latching Circuit: The latching mechanism can be inhibited by a 0 on inputs 4 and 14HMM, providing flexibility in controlling when the latch should be cleared.
Resetting the Latch: To reset the latch and clear the trip indication signal, the push button on the front of the card must be depressed. This manual reset ensures that operators have control over the system's trip state and can intervene when necessary.
The Speed Control Sensor Card plays a crucial role in monitoring and safeguarding turbine operations. By providing real-time feedback on turbine speed and allowing for automatic trip signals when unsafe conditions are detected, the card helps prevent turbine damage due to excessive speeds. Additionally, the ability to latch the trip indication and manually reset it ensures that operators have full control over turbine protection systems, improving overall safety and operational reliability.

What is IC3600QOXC?
It is a Speed Control Sensor Card developed by GE under Mark I and II series.
What are the output signals of the card?
The card has two output signals, TRP1 and TRP2. These signals are activated when the turbine speed is above a predetermined threshold. The card also provides a trip indication signal on TPL when the turbine speed exceeds or falls below safe operating limits.
What is the purpose of the latching circuit on the card?
The latching circuit holds the trip indication signal on TPL to prevent the turbine from continuing operation at unsafe speeds. The latch ensures that once the turbine speed exceeds the safe threshold, the system will stay in trip mode until manually reset.
How can the latching circuit be reset?
The latch can be reset by pressing the push-button on the front of the card. This clears the trip indication and allows the turbine system to return to normal operation.
Can the latching circuit be inhibited?
Yes, the latching circuit can be inhibited by applying a 0 to inputs 4 and 14HMM. This gives the operator control over when the latching should be active or inactive.
What happens if the turbine exceeds the predetermined speed?
When the turbine speed exceeds the predetermined threshold, the card activates the TRP1 and TRP2 output signals. This serves as a trip signal, indicating that the turbine is operating at unsafe speeds and that the system will take protective actions.
