Andover Controls D0-4-0 RS-485 Interface Module

Andover Controls D0-4-0 RS-485 Interface Module is a dedicated RS-485 interface device from Andover Controls that provides the physical layer needed for serial communication over an RS-485 network. The D0-4-0 model is intended to connect building automation equipment to a shared RS-485 bus, enabling differential signaling over twisted-pair cabling to communicate with other controllers or remote devices. RS-485 interfaces support multipoint networks and are valued for noise immunity and longer cable runs in industrial and commercial environments, making them a common choice for distributed control systems. Within a building automation environment, the module acts as the interface point between a controller and remote devices on the RS-485 network. As part of Andover Controls' range of control interfaces, the D0-4-0 emphasizes reliable, serial communications for distributed control architectures. It is designed to integrate with standard RS-485 networks used across building management projects, enabling seamless interoperability with other devices that follow the RS-485 standard.
