Accessories

1. Overview

Industrial automation and controls accessories are critical components that enable precise monitoring, control, and optimization of industrial processes. These accessories include sensors, actuators, human-machine interfaces (HMIs), and communication modules, which work together to enhance operational efficiency, safety, and reliability in manufacturing, energy, and other sectors.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Sensors	Convert physical parameters (temperature, pressure) into electrical signals	Production line temperature monitoring
Actuators	Execute mechanical actions based on control signals	Robotic arm positioning systems
Controllers	Process input data and generate control outputs	PLC-based assembly line control
HMI	Provide operator interface for system interaction	Factory floor control panels
Safety Components	Ensure emergency shutdown and hazard prevention	Machinery safety interlock systems

3. Structure and Composition

Typical accessories consist of:

Industrial-grade housing (plastic/metal)
Embedded circuit boards with signal processing components
Electrical/communication interface modules (e.g., Ethernet, RS485)
