RIB®, Power Metering, and BACnet®

Tech Tuesday Blog Banner

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.

RIBPM413-BC-KIT Power Meter Kit

If you are also in need of a place to mount this that will comply with installation requirements and code, look no further than our BACnet® Power Meter Kit, RIBPM413-BC-KIT.

This kit includes the BACnet® Compatible Power Meter circuit board, which will collect and send all the data points to the BAS controller. Also included in this Kit is the fuse holder, fuses, and disconnect switch. Everything is prepackaged and prewired in an 18-gauge steel enclosure.

  • Revenue Grade Power Meter
  • Includes 16 Amp rated Disconnect Switch
  • Includes Fuse holder with three 2 Amp rated fuses
  • Dimensions: 8.3” H x 7.7” W (9.2” W with switch) x 3.9” D
  • Made in the USA with Global Materials

Current Transformers

The last piece of the puzzle is current transformers to monitor the load, and we have those as well. We offer a wide range of solid core, split core, and Rogowski coil CTs that work with our power meter and are revenue grade.

  • 5A – 10,000A range models
  • 333mV output, full-scale
  • ETL Approved
  • UL 2808 & IEC 61010-1/2 & CSA C22.2
  • CE Approved
  • Indoor use only
  • Made in the USA with Global Materials

The MOD series of devices are optional modules that connect to the output of the Rogowski Coil CTs and convert the output to the 0.333 V analog scale for use in other Power Monitoring systems. The MOD series has options for one, two, or three-phase power feeds. The MOD series devices are DIN rail mountable, are ETL approved, and require 12 Vdc for input voltage.
