Application
**Industrial Automation:** This involves communication between programmable logic controllers (PLCs), human-machine interfaces (HMIs), variable frequency drives (VFDs), sensors, and other industrial equipment. It plays a crucial role in monitoring and controlling the production process.
**Building Automation:** In intelligent building systems, this technology connects air conditioning units, lighting, security systems, access control systems, and other equipment. It helps monitor and manage the building's internal environment and equipment, enhancing intelligence and energy efficiency.
**Remote Monitoring:** This application is used for remote monitoring systems, including the remote reading of data from electricity meters, water meters, and gas meters. It also allows for the status monitoring and control of remote equipment, facilitating easier management and maintenance.
**Data Collection:** In scenarios where data must be gathered from multiple sensors or devices, RS485 wires provide a reliable method for data transmission, ensuring accurate data collection and transfer.
**Telecommunications:** In telecommunications infrastructure, this technology connects and controls remote communication equipment such as base stations and switches, ensuring the stable operation of the communication network.
Installation Instructions
**Ordinary Type**: This type is typically made of two twisted copper wires that are wrapped in an insulating sheath. It is designed for environments with minimal interference.
**Shielded Type**: Building on the ordinary twisted pair cables, the shielded type includes an additional shielding layer. This can be made from aluminum foil or a polyester composite tape, as well as tinned copper braided mesh. This shielding offers improved protection against interference, making it suitable for environments with strong electromagnetic interference, such as industrial sites.
**Armored Type**: This type takes the shielded version a step further by adding an armoring layer, which may consist of steel belt armor or steel wire armor. Armored cables are designed for use in areas with severe interference, a high risk of rodent damage, and requirements for lightning protection and explosion resistance. They effectively protect the cable from external mechanical damage.
