GE IC3600STDC1 Time Delay Card

الوصف

The GE part number IC3600STDC1 is a Time Delay Card. This is a specialized electronic circuit board used in GE Speedtronic Mark I and Mark II series turbine control systems. Its primary function is to introduce a precise, predetermined delay in a control sequence.

Function and Key Features

In a complex industrial control system like a turbine, certain events must be carefully sequenced to ensure safe and efficient operation. A time delay card provides the necessary function to hold or delay a process for a specified period.

• Timing Control: The card allows for a specific action or process to be delayed by a set time interval. This is critical for synchronizing different steps in an automated sequence, preventing system overlap, and ensuring the safety of the equipment. For example, it might delay the ignition of a gas turbine until after a certain period of purging to ensure all explosive gases are cleared.
• System Synchronization: By providing a controlled delay, the card ensures that different components of the system activate in the correct order. This is vital for complex processes like turbine startup and shutdown, where a mis-timed action could cause significant damage.
• LED Indicators: The card is often equipped with LED indicators that provide visual feedback on its status. These indicators can show whether the card is receiving power, its current status, the progress of the time delay, or if a fault has been detected. This is a crucial feature for quick troubleshooting and diagnostics.
• Robust Design: Like all GE industrial control boards, it’s built to withstand the harsh conditions of a power plant, including vibration, temperature fluctuations, and electromagnetic interference.

Applications

The IC3600STDC1 is a legacy component, so it is primarily used in power generation facilities that still operate GE’s older Mark I and Mark II turbine control systems. It’s an essential component for:

• Turbine Startup/Shutdown: It provides the necessary delays for a safe and controlled startup or shutdown sequence.
• Safety Interlocks: It can be part of a safety system, for example, by delaying an action until a sensor confirms a condition is safe.
