Danfoss upgrades MCX controllers
23rd September 2020
DENMARK: Danfoss says upgrades to its MCX15B and MCX20B controllers deliver embedded connectivity, stronger web security, and enhanced performance.
The new MCX15B2 and MCX20B2 controllers are also said to mitigate the industry’s most common difficulties when designing connected HVAC systems and smart buildings. In addition, they provide improved compressor control logic for VZH inverter scroll compressors.
To advance WEB server and TCP protocol connectivity, the MCX15B2 and MCX20B2 controllers are ethernet-enabled with web server features and Modbus/TCP protocol, CAN bus as a fieldbus towards other controllers, remote user interfaces, up to two Modbus RS485 opto-isolated serial interface, and USB access for easy software uploading and datalogging.
The MCX15B2 and MCX20B2’s basic architecture and increased safety monitoring are said to ensure a solid security base. Secure protocols, cipher suites, protected keys and certificates, strict user and access authorization, strong safeguarding policies, and frequent safety updates are said to enable users to track and respond to security threats quickly and easily.
With the increased capacity and speeds available for customer software applications, managing additional languages, datalogging, and the creation of webpages, the MCX15B2 and MCX20B2’s enhanced performance shines above its predecessors.
The units’ compressor management for VZH scrolls is described as best in class. They can perform time- and level-based functions for both envelope and discharge gas temperature control and single oil management, such as generating alarms and increased speed and maintenance when necessary.
