RS-485 I/O

RS-485 I/O modules play an important role in industrial data communication, especially in environments where robust and reliable serial transmission is required. The RS-485 protocol is an evolution of the RS-232 protocol and enables bidirectional communication over a differential line, resulting in increased noise rejection and longer range. RS-485 I/O modules use this protocol to connect between control units, sensors, actuators, and other external devices.

The use of RS-485 I/O modules offers a number of advantages. Because of its differential transmission method, RS-485 is less susceptible to electromagnetic interference and noise, resulting in more reliable data transmission in demanding industrial environments. The protocol also supports point-to-point or multi-drop configurations, where multiple devices can communicate on the same line, reducing cabling costs.

RS-485 I/O modules are often used in applications where data must be transmitted over longer distances, such as factories, building automation systems and process control systems. They are well suited for communicating with sensors and actuators distributed in different locations, as they can reliably transmit signals over longer distances.
