5464-024 Woodward overspeed protector

The 5464-024 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward 5464-024
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- 5464-024 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

2） DLT/SDLT tape drive
DLT (digital linear tape) technology, also known as digital linear tape technology, was first developed by DEC in 1985 and is mainly used in VAX systems.

Later, it was purchased by Kunteng Company and its technology was improved. DLT adopts linear recording technology, which is characterized by large

capacity and high speed, but at a higher price. DLT products are mainly used in the mid to high end server market and tape library application systems,

with a rapidly growing market share. At present, the capacity of DLT drives varies from 10GB to 40GB, with data transfer speeds ranging from 1.25MB/s to 5MB/s.

Super DLT (SDLT) technology was launched by Quantum Corporation in 2001.

The capacity of SDLT is 110GB, nearly three times that of DLT tape series products, and the transfer rate is 11MB/s, twice that of DLT. Although SDLT

has made many improvements to DLT tapes, it is still compatible with the earliest DLT tapes and has good read back compatibility with DLT 4000, 7000, and 8000 drives.
（3） VXA tape drive
VXA is Exabyte”s latest tape drive technology positioned in the low-end market. The first generation product of VXA technology, VXA-1 tape equipment,

has a single machine capacity of 66GB and a data transfer rate of 6MB/s (compressed). Its capacity and performance are three times that of DDS-3, and its speed is the same as DDS-4, but its capacity exceeds DDS-4.
（4） AIT Tape Drive
AIT (Advanced Intelligent Tape) was developed by Sony and launched on the market in 1996. AIT-3 can write 100GB (260GB, compressed) of data to a

230m long 8mm magnetic tape at a sustained data transfer rate of 12MB/s (31MB/s, compressed), which is as high as the storage capacity provided by LTO media, but occupies only one-third of the space of LTO.
