The CENTRAX CU3000 combines in one housing for panel mounting the functionality of a highly accurate measurement device for power applications with the possibilities of a freely programmable PLC. Thus, in many cases, there is no need for a separate PLC, a control system, a remote display or an additional data collector.

The measurement part of the CU3000 determines in high quality more than 1500 state, energy consumption and power quality information. The control application (based on CODESYS) can then process these data logically, use them in control algorithms or respond to power generation or consumers in accordance with the application. The device can communicate with the process environment via freely selectable I/Os and via Modbus interfaces.

  • Technical characteristics

    The Control functionality is provided in three performance classes:

    • BASIC (available): Flexible processing of the data of the measurement device with full use of the I/O functionality
    • ADVANCED (not yet available): In addition, the possibility to read and use data from other measurement instruments via Modbus RTU/TCP, as well as to trigger time-depending processes
    • PROFESSIONAL (not yet available): For creating your own web visualization and to use the local display for self-defined visualizations

    Basic functionality

    • Direct measurement up to 690V, CATIII
    • Condition monitoring: class 0.1 (U/I), class 0.2 (P/Q/S)
    • Energy consumption analysis, class 0.5S (meters, load profiles, trend analysis)
    • Harmonic analysis acc. IEC 61000-4-7
    • System imbalance monitoring
    • Universal process I/O
    • Graphical measurement displays
    • High resolution color TFT display

    Ethernet interface

    • Device parameterization via WEB browser
    • Firmware update
    • Measurement display
    • Measurement acquisition via control system (Modbus/TCP server)
    • ADVANCED function: Measurement acquisition from other devices (Modbus/TCP master)
    • Service and maintenance

    Options

    Modbus/RTU interface

    • For measurement acquisition via control system (as slave)
    • ADVANCED function: For measurement acquisition from other device (as master)

    Process I/Os
    In addition to the standard I/Os (1 digital input, 2 digital outputs) up to four I/O extensions can be implemented in the device. You may select from the following extensions:

    • 2 relay outputs
    • 2 analog outputs ±20mA
    • 4 analog outputs ±20mA
    • 4 S0 digital inputs active
    • 4 S0 digital inputs passive

    Data logger

    • Periodical data: Load profiles, meter readings
    • Disturbance recorder: Recording of voltage events (acc. PQ standard IEC 61000-4-30)
    • Events: Logbook of the occurrences of system events
