Production Specification

The OPTOEMU-SNR-DR2 energy monitoring unit monitors the electrical energy used in your facility and then signals electrical equipment to turn on or off in response to a request from an electric utility, demand response aggregator, or curtailment service provider (CSP). To reduce peak energy use that triggers demand charges, electrical equipment loads can also be shed on predefined usage thresholds.

OPTOEMU-SNR-DR2 monitors up to two KY or KYZ pulsing devices, such as a pulsing meter or submeter, and up to 64 data inputs from Modbus devices over serial and Ethernet. The unit sends this data to an online service of your choosing, so you can see and analyze energy usage. The unit can also send energy data to control systems and company databases.

The unit's four signal relay outputs can be used to automatically respond to a DR event by signaling equipment such as HVAC fans and chillers to turn on or off, or signaling existing energy or building management systems to perform load shedding. Each Form C output can be wired for normally open or normally closed.

The OPTOEMU-SNR-DR2 communicates with online services and computer networks over a standard 10/100 Mbps wired Ethernet network. An easy-to-use utility program for configuring the unit is included. You can download this OptoEMU Sensor Manager for free; it also comes on a CD with the unit.

If you need wireless communications, see the OPTOEMU-SNR-DR1.

If you need to monitor voltage and current directly from an electrical panel or electrical equipment (not through a pulsing meter or Modbus device), see the OPTOEMU-SNR-3V.
