Novus DigiRail-VA - 8811509405

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

Features:

• It measures and calculates:
• Voltage: 0 to 300 Vac (True-RMS)
• Current: 0 to 5 Aac (True-RMS) - It does allow the use of CTs for higher current applications
• Active Power
• Reactive power
• Apparent power
• Frequency: 45 to 65 Hz
• Power Factor: 0.00 to 1.00
• All in a single, compact, DIN rail mounting unit featuring RS485 /Modbus-RTU interface as standard (baud rate from 1200 to 115200, configurable parity) allowing easy access to all the parameters by any SCADA package or Modbus capable PLC
• Analogue retransmission (user selectable 4-20mA and/or 0-10V – all by software; no jumpers)
• Any one of the values can be re-scaled and retransmitted using the onboard analogue outputs
• Full 2500 Vrms isolation between the high voltage/current inputs and the low voltage signals
• Protects your upstream instruments
• High accuracy measurements
• Accuracy of Voltage, Current & Power readings over RS485 is +/- 0.25% and +/- 0.5% over the Analogue Retransmission
• Accuracy of the Frequency and Power Factor readings over RS485 is +/- 0.5% and +/- 1% over the Analogue Retransmission (Please note, however, that the DigiRail-VA is not intended for and should not be used for commercial energy metering applications)
• Wide-Ranging 10-40Vdc power supply requiring just 2.5 W. It is suitable for most standard low voltage industrial supplies.
