Unitronics GW-KNX1 KNX gateway for integrating Unitronics PLCs with KNX building automation systems using KNX, Modbus RTU and Modbus TCP communications.
£600.25
The Unitronics GW-KNX1 is a powerful KNX to Modbus gateway designed to seamlessly integrate Unitronics PLCs with KNX-based building automation systems. It enables communication between Unitronics Vision and UniStream controllers and devices operating on KNX networks, making it ideal for building management, HVAC, lighting control and energy management applications.
Designed specifically for building automation integration, the GW-KNX1 automatically converts Modbus communications into KNX protocol communications, allowing PLC-based automation systems to communicate with KNX-enabled devices. Configuration is simplified through dedicated KNX configuration tools available within Unitronics software environments.
Its compact industrial design, support for multiple communication protocols and wide operating temperature range make the GW-KNX1 an ideal solution for both commercial building automation and industrial infrastructure projects requiring reliable interoperability between PLCs and KNX systems.
The GW-KNX1 enables Unitronics PLCs to exchange data directly with KNX-enabled building automation devices. This allows lighting systems, HVAC equipment, security systems and energy management devices to be integrated into a unified automation platform.
By translating Modbus communications into KNX protocol communications, the gateway simplifies system integration and enables industrial PLCs to become part of modern smart building infrastructures without requiring complex custom development.
