    Weatherproof Totalisor

    The CO4HWP four digit LED Totaliser is a 120/240 VAC or 18-36 VDC powered microprocessor based totaliser that incorporates a four (4) digit 100mm digit height LED display in a weatherproof surface mount enclosure. It has dip switch selectable input for, CMOS logic, open collector transistor, reed switch, hall affect and turbine meter (20mV peak to peak minimum).to produce a total in the units of your choice using a field programmable K factor.

    They incorporate field programmable totalising rates and a 24 VDC isolated supply for powering remote sensors. The CO4HWP is supplied in a surface mount IP65 weatherproof enclosure. Screw terminal electrical connection is included.

    Input Details
    • The instrument counts input pulses and displays the totalised value on a four (4) digit LED display. The input is dip switch selectable for dry relay contact, open collector, turbine meter, reed or proximity switch and CMOS logic
    • CMRR greater than 86db
    • NMRR greater than 100db

    Four (4) digit 100mm digit height high contrast light emitting diode (LED) with a wide viewing angle and a viewing distance of 20 metres

    Decimal Point

    Programmable from the front panel to display units or 0.1 units.

    Count Integrity

    Contact bounce elimination circuitry enable error free counting even in the most difficult application. The count is stored in eeprom.

    Remote Reset

    By connecting a normally open push button between terminals 1 and 6.

    Environmental Parameters
