Types and Functions of Mechanical Couplings and Clutches
Understanding Mechanical Couplings
Durable Couplings are essential machine components used during power transmission. Their primary functions involve connecting shafts, facilitating mounting, and simplifying maintenance.
Drive Couplings
These couplings provide a direct link between two shafts, typically transmitting rotational motion. They often involve plates or screws connecting the elements, allowing for power transfer but generally not accommodating misalignment unless specifically designed to

Fire Extinguishing Installations
BIE (Fire Hose Stations)
A pressurized water fire extinguishing system comprising:
- Connection to a public water supply or fire pumping equipment.
- Network of pipes for water distribution.
- Hose reel (BIE).
Sprinklers
Individual, automatic sprinkler heads connected to a separate cold water pipe, capable of withstanding a pressure of at least 150 meters of water column (mca), and composed of:
- Water intake from the general network, independent
CT Installation: Components, Classifications, and Features
CT installation is provided with one or more processors, reducing high and low voltage switchgear and working with precise complementary functions. The function of a CT is to distribute electricity to different voltages while simultaneously allowing the connection to lines and networks at any point. CTs are classified in five ways:
Classification by Food (Supply)
- In Point: There is only one supply line connected to the derivation of the main network.
- In Step: Has one input and one output line to another

Key IoT Protocols, Cloud Concepts, and Device Fundamentals
What is Modbus?
Modbus is an industrial communication protocol developed by Modicon (now Schneider Electric) in 1979 for programmable logic controllers (PLCs). It follows a master-slave architecture, where a master device initiates requests, and slave devices respond. Modbus operates over serial lines (RS-232, RS-485) and TCP/IP networks. It supports three modes:
- RTU (Remote Terminal Unit): Binary encoding.
- ASCII: Text encoding.
- Modbus TCP: Ethernet-based communication.
It is widely used in SCADA systems,
