    The DI45 Powered Process Indicator is an advanced instrument that have been designed and manufactured to stringent specifications.

    The instruments have been designed to accept all the standard analogue process signals. The input measurement is shown on a high contrast LED display.

    The DI45 incorporates an LSI CMOS 20,000 count dual slope integrating analogue to digital converter which is designed to reject electrical interference that normally abounds in industrial environments. The front panel of the DI45 series are sealed to IP65 and includes screw terminal electrical connection.

    Input Details
    • The instrument has a bipolar differential input. To realise the accuracy a temperature compensated band gap reference is used in the ratio metric measurement system. Full scale ranges of 20mV to 200VDC 200uA to 2Amps and 4-20mA are acceptable.
    • CMRR greater than 86db.
    • NMRR greater than 100db.
    • A 4.5 digit high contrast light emitting diode (LED) with a wide viewing angle.
    • The DI45 has a digit height of 14.2mm.
    Decimal Points

    Four (4) position user selectable by push on jumper for formats 1000.0; 100.00; 10.000; 1.0000

    Environmental Parameters
