    CO48

    Process Totalisor

    The CO48 Powered Process Totaliser is a programmable instrument that has been designed to accept pulses from open collector, hall affect, turbine meters or 24VDC voltage pulse. The input measurement is shown on either a high contrast eight (8) digit LED or LCD display.

    • Totalise with field programmable factors
    • Flow rare display
    • Memory retention for 10 years in power down for variables
    • Contact bounce elimination circuitry
    • Low cost - High performance
    • Screw terminal electrical connection
    • High contrast LED display of 8 digit of 10mm character height or a 8 digit 9.5mm single line LCD display  
    • Panel mounting
    • Isolated 24VDC @ 30mA sensor supply
    • 120 or 240VAC 47-63 Hz supply or factory fitted 12 to 24V DC isolated supply
    • Touch switch programming of display intensity, decimal point position, scaling factor
    • Applications include adding parts on a production line and totalising events
    • Emc compliant

    The instruments incorporate field programmable totalising rates and a 24VDC isolated supply for powering remote sensors. The CO48 is supplied in a panel mount 48 x 96 mm enclosure. Screw terminal electrical connection is included.

    Input Details

    • The instrument accepts an input from 0 to 2KHZ and is dip switch selectable for open collector, reed, Hall, Namur and turbine signals (from 20mV peak to peak).
