NDL8000 SERIES - AC Voltage and Current Data Loggers
2
Two keys for START/STOP of recording and data logger auto-diagnosis.
Two LEDs for data logger status indication.
Easy to use. Few simple operations are required, the instructions are printed directly on the data logger panel (see panel picture below).

L-L. The
connection is carried out by safety connectors.
• Programmable PT Value for medium and high voltage networks
• Measurement and calculation of L- N, L- L and system values
Current measuring models
• 1, 3 or 4 channels for single and three-phase systems, with or without neutral current measurement, or as indipendent channels.
• Internal calculation of neutral current when only 3 transducers are used.
• Standard inputs for flexible Rogowski coils without the need for external integrator.
• The input sensitivity can be configured on request from 100mV to 10VAC-DC to connect any type of current transducer.
• Programmable current transducer full scale. Memory
• 2MBytes FLASH type data memory expandable up to 4MBytes. Data are retained even if power supply is down (exhausted or removed battery).
• Recording parameters programmable from PC by the TrueGraph software.
• Three selectable recording modes: fill-in, wraparound and wraparound with an auto-decreasing recording rate for recording time extension when memory is full.
• Built-in RTC for time reference.
• Programmable recording rate between 1 second and 24 hours.
Communication
• Optoisolated RS232 serial communication port
• The serial port is powered directly from PC RS232
• Programmable communication speed up to 19200 bps . Keys and commands
