OptoEMU Sensor (Energy

Monitoring Unit)

Description

The OptoEMU Sensor

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 such as

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

Connecting to Electrical Devices

The OptoEMU Sensor can connect to a variety of metering

devices that emit pulses. It can also connect directly to

electrical circuits using current transformers (CTs) with a 0.333

VAC secondary.

The Sensor can monitor energy devices in both ways,

simultaneously:
