RIB®, Power Metering, and BACnet®
One of the newer products for Functional Devices is the Power Meter. This revenue grade power metering device is great for single or three-phase power systems. BACnet® communication is built in, so integrating this into the building automation system is as easy as terminating the MS/TP connection and discovering it on the controller. Multiple current transformers (CTs) may be used to meter energy usage. The power meter circuit board is mounted on our MT212-4 track, so installation is a breeze.RI
