Opto 22 has diversified and expanded its Groov RIO edge I/O series with the introduction of a new energy monitoring unit (EMU), engineered to assist machine operators, plant managers and financial analysts in understanding electrical costs and track changes in load that could give early warning of equipment faults.

Using 0.333 V, 1 V, or 5 A current transformers (CTs), groov RIO EMU measures live AC power and energy consumption from any three-, twin-, or single-phase load up to 600 V, while providing 64 simultaneous field measurements and calculated values directly to analytics software, databases, and other connected systems.

For industrial rate-payers, operational costs may be elevated due to a lack of visibility into energy consumption. Small changes and improvements to operations can add up to a big difference, reducing power consumption and leading to major cost savings. However, in the absence of strategic data collection, it can be difficult to identify and make these improvements.

Furthermore, measuring power draw at the machine level can be highly effective in monitoring the health of the machine, detecting potential issues and making prompt adjustments to things like filter pressures, bearings, lubrication and motors, without instrumenting each component.

The groov RIO EMU module measures AC RMS voltage and current for up to three phases (Wye or Delta) and is rated to UL 61010-3 measurement category III. From the measured field inputs, additional values are calculated for each phase including true, reactive, and apparent power; power factor; frequency; and net energy; as well as combined totals for all phases.

Its small size enables the unit to be installed at the point of use, allowing for granular measurement of electrical loads: solar power generation, heating/cooling systems, pumps and many more besides.

Groov RIO EMU is based around Opto 22’s outstanding edge I/O platform. It features Power over Ethernet (PoE) and a broad range of operating temperatures for simplified installation. Module operation and data distribution are safeguarded with cyber security features, which include a configurable firewall, mandatory user authentication and SSL/TLS encryption. IT and OT communication options are both supported, along with a full REST API, VPN client, and MQTT/Sparkplug client.

The unit is compatible with conventional control programming and SCADA systems. Data access is also possible via the embedded Node-RED IoT programming environment and IT programming languages like Java, Python and C++.
