Description
The OptoEMU Sensor
™
Energy Monitoring Unit monitors the
electrical energy used in your facility and then delivers that
data to online software applications or control systems. The
OptoEMU Sensor gives you the detailed, real-time data you
need to analyze energy consumption and reduce energy
costs.
Why Monitor Energy?
Traditionally, the cost of energy has been considered an
overhead cost. Utility bills show few details about when and
how electricity was used, and they arrive long after the energy
was consumed.
However, new energy pricing structures are changing
traditional ways of looking at energy costs. Increasingly,
commercial and industrial businesses are finding that they can
significantly reduce energy costs by managing energy in the
same way as other business costs such as people, assets, and
inventory. Energy management represents significant
opportunities to improve the bottom line.
Reducing energy costs does not require complex or expensive
technology; it requires basic information. That information
starts with gathering detailed, real-time data through the
OptoEMU Sensor.
Viewing Energy Data
Real-time and historical energy data gathered by the
OptoEMU Sensor is viewed online through a secure software
service. You choose the service that’s best for your business.
The OptoEMU Sensor sends energy data directly to the service
you choose, and you can view the data from any authorized
computer or mobile device in accordance with the service you
purchase.
Using Energy Data in Other Systems
Energy data from the OptoEMU Sensor can also be sent to
other systems for use there. Sensor data can be incorporated
in a PAC Control strategy, a PAC Display HMI, and control
systems that communicate through Modbus/TCP or OPC.
In addition, energy data can be sent to common SQL
databases such as MySQL and SQL Server.
Using Sensor data in these other systems, you can manage
energy usage and costs in detail. For more information on
using energy data in other systems, see form 1958, the
OptoEMU Sensor Communication Guide.
Connecting to Electrical Devices
The OptoEMU Sensor can connect to a variety of metering
devices that emit pulses. It can connect to Modbus devices
over serial or Ethernet. And it can also connect directly to
electrical circuits using current transformers (CTs) with a 0.333
VAC secondary.
