CO8WP Process Totalisor
The CO8WP Powered Process Totaliser is a 85 to 240VAC or 10-40VDC powered microprocessor based totaliser that incorporates an eight (8) digit 25mm digit height light emitting diode (LED) display in a weatherproof surface mount enclosure. The instrument can be configured to count up/down, elapsed time, time of day clock, events or totalise flow with programmable K factor. It accepts a pulse input from a dry contact closure, proximity switch, photo-electric switch, and open collector transistor or 24VDC source. The count value is maintained during loss of power for a minimum period of ten years in eeprom.
