GENERAL FEATURES:
The 2108 Series is a totalizing counter housed in a DIN-sized (24 x 48mm)
enclosure. The 2108 has an eight digit 7mm high LCD display. The count
input (slow speed) and reset input can be by contact closure and by NPN
open collector transistor. The high speed input (7 kHz max) requires a 4
to 30 VDC voltage pulse and is compatible with 2 and 3 wire DC proximity
switches and encoders. The unit is powered by a 3 volt lithium battery with
an eight year life. When changing the battery, the current count value is
retained long enough to allow battery replacement without losing the count
value. The unit can be set remotely or from the front panel. The front panel
reset can be enabled or disabled with jumpering of terminals on back of unit.
