Novus DigiRail VA Single Phase Voltage/Current Transducer with RS-485 and USB
The Novus DigiRail VA is a DIN-rail mount measurement transducer for single phase AC power. It can measure voltage, current, power (real, apparent, reactive, power factor) and frequency up to 300 VAC and 5 A AC. It has 4 to 20 mA and 0 to 10 V retransmission outputs and RS-458 and USB for Modbus RTU communication.
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 retransmit them in both analog and digital ways. All in a single, compact, DIN rail mounting unit featuring RS-485 / Modbus-RTU interface as standard allowing easy access to all the parameters by any SCADA package or Modbus capable PLC
Features:
- Analog retransmission channels fully configurable by software
- It can measure Voltage, current, frequency, power factor, active, reactive and apparent power
- 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
