Details
Woodward 5437 - 1119 is a ProTech - GII module. The following is its detailed information:
Brand: Woodward
Model: 5437 - 1119
Type: Spare module for safety device
Application: It is applicable to the old ProTech - GII model. It provides hardware and software requirements and conversion guidelines for converting legacy ProTech - GII models to Woodward's latest ProTech - GII models in the field. Besides, it is a backup module for 8237 - 1246 rev D or later and 8237 - 1369 safety devices for ProTech - GII voting relay panels and panel mounting parts.
Related Certifications: It has obtained IEC61508 SIL - 3 certification and complies with the provisions of API670 and API612.
Features
Acceleration Detection: It can be configured to protect turbines from high - acceleration events. The derivative of the speed signal is used to detect turbine acceleration and issue relevant trip commands.
MPU Detection: The speed sensor input of each module uses a special MPU open - wire detection circuit to verify the correct connection of the MPU before turbine operation and a special stall detection logic to verify the functionality of the MPU during turbine operation.
Automatic Overspeed Test Program: It can be configured to perform regular overspeed tests on each module, and then record and report the test results. When using this test program, each module uses an internal frequency generator to simulate overspeed conditions and execute the test according to the test sequence.
Anti - Sulfur Pollution: It uses a special conformal coating material, which has been proven to have excellent long - term protection performance under the H2S and SO2 gas levels specified in the international standard IEC 721 - 3 - 3 1994 - environmental class 3C2.
Online Maintenance: Thanks to its triple - module design, users can easily replace one of the modules (A, B, C) during the online and normal operation of the turbine. The device has a module - to - module learning function and a plug - and - play backplane structure, which makes replacement very convenient.
Online Testing: The ProTech - GII module can be manually tested from the front panel of the module or the Modbus communication port, or it can be automatically tested using the automatic test program function. Users can configure regular automatic overspeed tests, test one module (A, B, C) each time, record the results of each test, and stop the test if an error is detected.
Trip, Alarm and Overspeed Log: The log function records (saves to memory) all trips, alarms, trip valve response times and overspeed events. The trip record function uses a rolling buffer to record the last 50 sensed trip or alarm events and the last 20 overspeed events and related times. Each log file can be viewed from the front panel of the device or downloaded to a computer through the ProTech - GII service tool program. Each module uses non - volatile memory to ensure that all recorded events are saved even in the event of a power failure.
Real - time Clock: Each module uses a real - time clock to ensure accurate time recording, and a special time - averaging function is used between modules to ensure clock synchronization between modules.
