  • Overview

  • Technical details

  •  

    Application

    • The 5725 measures, scales, and displays frequency signals found in many process speed and flow rate applications.
    • The indicator can measure the period of the frequency, useful for displaying the elapsed time between events.
    • The 5725D has two SPDT setpoint contacts and a 0/4...20 mA output for process control.
    • The installed display provides IP65 environmental sealing, and additional protection is provided by the optional 8335 splash proof cover.

    Technical characteristics

    • 4-digit display with 13.8 mm high, 14-segment LED digits and adjustable decimal point.
    • Indicator is scalable from -1999 to 9999.
    • Scrolling help text makes programming easy.
    • Customizable trigger levels allow measurement of nearly any pulse sensor.
    • Built-in excitation source for measuring NPN, PNP, NAMUR and S0 sensors.
    • Fast response time of 1 cycle + 100 ms, and excellent accuracy of better than 0.05% of selected range.
    • The analog output current on the 5725D can be dampened from 0.1 to 60 seconds, and can handle up to 800 Ohms loop load.
    • The 5725 meets NAMUR NE21 recommendations for high performance in harsh EMC environments.
    • High 2.3 kVAC galvanic isolation, and an excellent signal/noise ratio of > 60dB.

    Mounting / installation / programming

    • Easy to mount 1/8 DIN (48x96 mm) panel meter with IP65 (type 4X) sealing.
    • Approved for marine applications.
    • Fully push-button programmable.
    • Password-protected.
