An RS485 hub allows multiple connections for devices compatible with the RS485 standard and is used to extend the usability an RS485 network. These hubs are very helpful in automation systems as well as building systems that need constant monitoring with a central control for the sensors, controllers, and actuators devices. It is able to collect data from different RS485 devices, store it for a short period, and send it to the right place. Additionally, it can split different portions of the RS485 network which helps reduce electrical noise, ensures proper communication between devices, and improves the overall reliability with scalability of RS485 devices networks.

What is RS485 used for?

RS485 is a serial communication standard used in industrial automation, security monitoring, and other fields. It enables long - distance communication between multiple devices in these applications.
RS485 has advantages like strong anti - interference ability due to differential signal transmission, long - distance communication capability, and the ability to support multiple devices on a single bus for distributed control systems.
In an RS485 network, devices are daisy - chained together using two wires (A and B). The positive terminal of one device is connected to the positive terminal of the next device, and the negative to the negative, following a proper grounding scheme for stable operation.
