The CO48 Powered Process Totaliser is a programmable instrument that has been designed to accept pulses from dry relay contacts, photo electric switches, open collector proximity switches or 24VDC voltage pulse. The input measurement is shown on a high contrast eight (8) digit LED display.

The instrument incorporates 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.

FEATURES

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

                                             TECHNICAL SPECIFICATIONS

Input Details

·The instrument counts input pulses and displays the totalised value on an 8 digit LED display. The input is optically isolated from the instrument and the signal can come from a dry relay contact, open collector transistor, reed switch, photo electric or proximity switch or voltage pulse. [CC = contact closure]

Output Details

·An output relay is provided with a contacts rated at 1 amp 240VAC resistive.

Display

·The CO48 incorporates a eight (8) digit 10mm character height (LED) with a wide viewing angle and a viewing distance of 5 metres.

Decimal Point

·Programmable from the front panel for no dp or 9999999.9

Scaling Factor

  • This is the pulses per unit of measure. It is programmable from the front panel and can be set to divide incoming pulses and totalise up.

Count Integrity

  • Contact bounce elimination circuitry combined with user programmable debounce periods enable error free counting even in the most difficult application.

Totaliser Memory

  • The instrument incorporates a running and a background total. In normal operation the reset button will only reset the running total.

Reset

·This is done by a normally open push button between terminals 1 and 6.

Environmental Parameters

·0-70 degrees Celsius.

·0-90% rh non-condensing.
