Building Automation and HVAC Controls

Open Protocol Relays

RIB® Open Protocol Field Devices can be used instead of a more expensive multi-output controller when a few more control points are needed, and a large controller is too much for the job. They can also be used when control points are widely spread throughout the job site. These controllers have been prepackaged to save the installer the time, trouble, and expense of buying separate components and assembling them on the job.
