The R9 Series Power Monitoring Unit is a compact all-in-one module that can measure up to 8 heavy current circuits with a common voltage input. An extension unit for additional 8 circuits (model: R9WTU-EP) can be attached to the side of basic unit. At the maximum of 16 measuring input unit provides for cost-effective multi-channel power monitoring solution for office buildings and manufacturing plants.

A discrete I/O extension unit (model: R9WTU-ED) is also available for 8 pulse inputs and 8 contact outputs. Pulse count signals such as gas/air pressure and water flow from other utility equipment, and production unit count signals can be taken in all together to the R9 unit for use with energy consumption rate calculation and energy efficiency improvement analysis of an entire manufacturing line.

 

 

Clamp-on Current Sensor Input

Current sensors that can take in a flexible range of 5 to 600 amperes directly to the unit can be fitted easily without need of extensive installation work. They are purchased independently to minimize introduction cost of the energy monitoring system that can be expanded later when more measuring points are needed.

Offline Monitoring

 

clip_image004The unit is equipped with a SD memory card slot. Data stored in its internal memory are transferred to the card at 0 minute every hour. A 4-GB SD memory can store information of 8 channels for approximately 16 years.

Energy (watthour) and pulse count input data per hour for each channel are stored with date/time. Voltage, current and power in addition to energy and pulse count per minute are also stored. All data are exported to the SD memory card every hour and saved in a CSV format file.

 

Online Monitoring

 

clip_image005Modbus RTU, Modbus TCP (Ethernet), CC-Link or LONWORKS interface types are available as standard. All parameters can be polled from a SCADA system on the PC: current, voltage, active/reactive/apparent power, power factor, frequency, active/reactive/apparent energy, harmonic distortion and date/time.

Contact outputs at the discrete extension I/O unit can be controlled from the host via the network for alarm and external count purposes.
