Climate control interface for multi V systems

The KET-RMB-211.CN.40 climate control interface is a versatile protocol converter for multi V systems equipped with a LG PMBUSB00A control unit, designed for rapid and straightforward integration between air conditioning control units and higher-level control systems such as BMS, BEMS, SCADA, PLC, Gateways, etc.

This intelligent device offers a standardized ModBUS interface to the controller (master), organizing the system and managed zones on different slaves while maintaining a uniform control structure for all. This architecture significantly simplifies the integration process. The consistency in the structure of control and monitoring registers within the KET-RMB series ensures uniform management of different air conditioning systems.

The amplified wireless connection with IEEE 802.15.4 protocol allows for remote installation of the interface in secondary panels, eliminating the need for costly and complex wiring, leveraging the benefits of wireless communication for greater installation flexibility.
