– It measures and calculates:
Voltage: 0 to 300 Vac (True-RMS)
Current: 0 to 5 Aac (True-RMS) – It does allow 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
– Analog 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 on-board analog 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 Analog Retransmission
– Accuracy of the Frequency and Power Factor readings over RS485 is +/- 0.5% and +/- 1% over the Analog 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.
