Unitronics GW-BAC1 BACnet gateway for integrating Unitronics PLCs with building automation systems using BACnet MS/TP, BACnet/IP and Modbus TCP protocols.
£502.25
The Unitronics GW-BAC1 is a high-performance BACnet to Modbus gateway designed to integrate Unitronics PLCs with modern Building Management Systems (BMS) and Building Automation Systems (BAS). It enables seamless communication between Unitronics controllers and networks using BACnet MS/TP, BACnet/IP and Modbus TCP protocols, making it ideal for HVAC, energy management and building automation applications.
Designed specifically for Unitronics automation platforms, the GW-BAC1 acts as a communication bridge between PLCs and BACnet devices. Using the UniBACnet Configurator software, engineers can quickly create configuration files and establish reliable communications between controllers and BACnet-based systems.
Its compact industrial design, broad protocol support and BTL-certified BACnet implementation make the GW-BAC1 an excellent solution for integrating industrial control systems into commercial building automation environments.
The GW-BAC1 enables Unitronics PLCs to communicate directly with BACnet-enabled building management systems. This allows automation engineers to integrate HVAC equipment, pumps, energy monitoring systems and other building services into centralised building automation platforms.
By translating communications between Modbus-based Unitronics controllers and BACnet networks, the gateway simplifies system integration whilst maintaining reliable data exchange across multiple building automation protocols.
