Electronic Totalizing Counters
A compact totalizing counter module for printed circuit board or panel
mounting. 8 digit, 8mm high, LCD display with backlight capability. An
external lithium battery (not supplied), is normally used to support
memory and counting. Current demand is typically 3µA quiescent, 6µA
counting. Backlight requires additional current.
Count speeds to 10kHz are possible. An internal contact-bounce filter
allows accurate counting from switch or relay contacts.
Electrical connections are made via rear pins which may be soldered to
a host printed circuit board or connected by pin terminals. A remote
electronic reset to zero is provided.
■ 8 digit high contrast LCD characters
