The BM-CH-20P-8G series of Sedona controllers are freely programmable, internet ready field controllers. They support multiconcurrent protocols and services such as BACnet, Modbus, TCOM, web services and both server and client services. Besides that, they can be programmed live, with our software programming tools.

The range complies with the Internet of Things by interfacing directly to cloud services, without an additional gateway or server. To power the application, the BM-CH-20P-8G series have a dual ARM processor engine and also a built-in web server (HMTL5, PHP,SQL).

Another exciting feature, is the openness, and its web friendly tools to enable third party tools to be deployed in addition to the workbench that we are all familiar with today. This platform meets the needs of simple control requirements and complex HVAC plants, such as chiller sequencing and roof top control.

The BM-CH-20P-8G series change the way Building Automation is deployed. Especially in multiple facilities and locations where a starter package can be deployed quickly, and cost effectively, without any additional hardware or middleware.

This range of BM-CH-20P-8G controllers allows the industry to extend their reach deeper and wider into all kinds of energy performance solutions. Ranging from retail stores, Schools, Commercial, Residential, Hospitals, Smart Grid and so on.
