OptoEMU: Energy Monitoring Made Simple

Start reducing energy costs with real-time energy data

OptoEMU Sensor and OptoEMU Sensor DR monitor your energy usage

Who 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. OptoEMU Sensor 3V and OptoEMU Sensor DR monitor the energy your facility uses in real time, then instantly deliver 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 Pulse Energy or eSight.

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 SNAP PAC System.

The OptoEMU Sensor DR adds demand response (DR) capability with four signal relay outputs. Demand response programs not only save money but can even become a source of revenue for your business.

With OptoEMU, you have exactly the information you need to make energy decisions and reduce costs. No wonder engineers like you picked the Sensor for the 2011 Engineers' Choice Award.
