CH
Series
LCD
Battery Powered Counter
Data sheet
Our
CH Series digital electronic counters have a small panel footprint
and are powered by a lithium battery (up to 7 year battery life). They
have a 7-digit LCD display, a push button reset, and accept a wide
range of inputs. Their reset function can be disabled if desired.
These self-powered LCD counters are designed for applications where
no external power is available, as replacements for electromechanical
counters, event counting and part counting. Some typical applications
include: Amusement machines, dispensing machines, ticket machines,
copiers, printers, utility meters and portable equipment.
