Functional Description
IS230TREA1AG01 is a Turbine Emergency Trip Terminal Board developed by GE. It is a part of the Mark VIe control system. The turbine emergency trip terminal board, an integral part of the Mark VIe system, collaborates with PPRO turbine I/O packs to ensure swift response during emergencies. It features customer input terminals accessible via two 24-point pluggable barrier terminal blocks, offering convenient connectivity and facilitating installation and maintenance. This modular design enhances flexibility and reliability while safeguarding turbine operations in critical situations.
Dedicated Speed Inputs
- When used in conjunction with PPRO I/O packs directly mounted on the TREA, the speed inputs offer users the flexibility of two distinct configuration options.
- In the first scenario, each PPRO I/O pack has the capability to receive a dedicated set of three speed inputs from their corresponding TREA terminal points, mirroring the configuration commonly found with SPRO setups.
Fanned Speed Inputs
- Alternatively, users can opt for a more consolidated approach by employing jumpers P1 and P2 on the TREA. This configuration allows the first three speed inputs, typically designated for the X pack, to be fanned out and distributed to the Y and Z packs.
- However, it's essential to note that with this setup, the terminal board points allocated for Y and Z speed inputs become inactive, effectively serving as no-connects. Consequently, these points should remain unused to avoid any operational complications.
Mismatch Detection and Alarm
- To ensure seamless integration and prevent configuration discrepancies, the PPRO incorporates a robust system for detecting mismatches between the jumper position and PPRO configuration.
- This detection mechanism is facilitated through a feedback signal provided by the TREA. In instances where such a mismatch is detected, triggering a misalignment between the jumper configuration and PPRO setup, the system promptly generates an alarm.
- This proactive alerting mechanism enables operators to swiftly identify and address any inconsistencies, thereby safeguarding system functionality and integrity.
Voltage Detection Inputs
- Min/Max Input Voltage Rating: The voltage detection inputs are designed to handle a wide range of input voltages, with a minimum rating of 16 V dc and a maximum rating of 150 V dc peak.
- Current Loading (Max Leakage): The module exhibits minimal current loading, with a maximum leakage current of 3 mA, ensuring efficient utilization of power resources.
- Detection Delay (Max): In terms of response time, the module boasts a detection delay of up to 60 ms, providing swift and reliable detection of voltage variations.
- Voltage Isolation:For enhanced safety and reliability, the voltage detection inputs feature optical isolation, offering a robust isolation rating of 2500 V rms for one minute.
- Surge/Spike Rating: The module is engineered to withstand transient voltage surges and spikes, with a surge rating of 1000 V peak for 8.3 ms, safeguarding against potential damage from electrical disturbances.
ESTOP/TRP Detection Input
- Voltage Range: The ESTOP/TRP detection input accepts voltages within the range of 24-125 V dc, with a tolerance of ±10% and minimum/maximum peak ratings of 18/150 V pk.
- Loading (Max): The maximum loading for this input is 12 mA, with a typical loading of 5 mA, ensuring minimal impact on the overall system power consumption.
- Delay (Max): The detection delay for ESTOP/TRP signals is limited to a maximum of 5 ms, with a typical delay of less than 1 ms, ensuring rapid response in critical situations.
MPU Pulse Rate Characteristics
- Pulse Rate Range: The MPU (Main Processing Unit) pulse rate can vary between 2 Hz to 20 kHz, offering versatility in signal processing and data acquisition.
- Pulse Rate Accuracy: With an impressive accuracy of 0.05 percent of the reading, the module ensures precise measurement and control of pulse rates, contributing to system reliability and performance.
- Input Circuit Sensitivity: The MPU input circuit exhibits high sensitivity, capable of detecting pulses as low as 27 mV peak, enabling the detection of subtle changes in speed or frequency, such as a 2 rpm speed variation.
