The DigiRail-VA is the latest addition to the successful and cost effective DigiRail family. Specifically designed for single phase AC power analysis applications, it is able to measure the most important AC signals and re-transmit them in both analog and digital signals.

4-20 mA  and 0-10Vdc Analog Outputs
There is both a 4-20 mA and 0-10Vdc analog output that can be used to transmit any of the measures in the AC inputs including:
• RMS Voltage
• RMS Current
• Active Power
• Apparent Power
• Reactive Power
• Power Factor
• Frequency

The outputs are fully scaleable via software and may also be enabled or disabled via software.  The outputs may also be set for a specified value on an error condition.

RS485
The RS485 interface of DigiRail-VA uses 3-wire communication (including the common) and operates as a Modbus RTU slave.  The measured values and configuration parameters may be read through the RS485 interface.  Operating parameters may also be set via RS485.

USB Interface
DigiRail-VA has a USB device interface, used for configuration and monitoring. The Windows operating system will detect the device as a virtual serial port, allowing the use access as a standard Windows COM port.

Software

DigiConfig Software

DigiRail Config Software
DigiRail-VA Configuration is done via the USB or RS485 interface  by using Modbus RTU commands. The free DigiConfig software, available as a download, allows for configuration of all DigiRail features as well as complete calibration and diagnosis. It automatically detects active devices in the Modbus network and permits configuration of all parameters.

FieldChart Supervisory and Data Acquisition Software (Lite version available as a free download)

FieldChartSoftware
FieldChart is a software used for monitor and register data acquired from NOVUS products. It generates real time trends and data lists that can be exported in usable formats like a spread sheet. There are two versions available: FieldChart-Lite and FieldChart-64C. The FieldChart-Lite can register 8 simultaneous channels and it is available for free. The FieldChart-64C can register up to 64 simultaneous channels
