Phoenix Contact introduces the Catan C1 controller, a versatile and secure platform designed to unify building systems and support sustainable, long-life projects amid increasing integration of protocols and security measures.
Phoenix Contact has added the Catan C1 to its building automation range, positioning the controller as an open platform for linking lighting, shading, HVAC and load management within one system. According to the company, the unit is aimed at system integrators and planners who need to combine different trades in both new-build projects and refurbishments, especially where existing KNX infrastructure is already in place.
The controller is built around PLCnext Technology, which gives it a more open software model than many conventional building controllers. Phoenix Contact says the platform supports familiar industrial engineering methods through PLCnext Engineer and access to applications from the PLCnext Store, while also allowing users to extend projects with software written for industrial automation. The company’s own product information lists 14 configurable inputs and outputs, three Ethernet ports, two RS-485 interfaces, two USB-C ports and KNX-TP connectivity, alongside local override via the Catan Control Panel.
A notable technical feature is the integrated KNX IP router in the base module. Phoenix Contact says this reduces the need for separate gateway hardware and simplifies installation in compact control cabinets. The system is also intended to unify communication across protocols including BACnet, Modbus and MQTT, with software support from partner Symcon helping to bring existing KNX topologies and other building systems onto a shared data layer. In practical terms, that gives operators a route to centralise control without ripping out established network architecture.
Security and sustainability are also part of the pitch. Phoenix Contact says the controller includes Secure Boot, signed software and TPM-based device identities to protect the system from unauthorised access, while the platform has been developed according to circular-economy principles and is Cradle to Cradle Certified. The company argues that this combination makes the Catan C1 suitable for long-life building projects where energy efficiency, regulatory compliance and transparency over the product lifecycle are increasingly important.
