Start reducing energy costs with real-time energy data

OptoEMU SensorsWho pays attention to your energy bill? It's just a number at the end of the month, with no information about how you got there.

Yet controlling energy costs can significantly improve your bottom line.

To reduce energy costs, you need detailed data about energy use. The OptoEMU Sensor DR monitors the energy your facility uses in real time, then instantly delivers that data over your existing wired or wireless Ethernet network.

Connect OptoEMU to pulsing meters, Modbus devices, electrical panels, and equipment. View and analyze the data online using a software service such as eSight or build your own operator interface and send data to software programs with groov Family products.

Send energy data to control systems, using open standards such as Modbus and OPC. Send data to company databases. Send data to Opto 22's groov EPIC System or SNAP PAC System.

The OptoEMU Sensor DR adds four signal relay outputs, opening the possibility of demand response. Demand response programs not only save money but can even become a source of revenue for your business.
