CUB4CL20 - 

Self-Contained batteries eliminate the need for external power and prevent loss of count if power fails. Also provides for remote or portable applications. Battery operation also means elimination of shock hazard and allows the use of 2-conductor bell wire for count signals and micro-power input signals. Batteries are easily replaceable (2 “N" Cells, alkaline) and average battery life is four years. Various count inputs allow use with switch contacts or high speed pulse outputs from electronic sensors and circuits. The reset function can be disabled, set up for front panel reset, remote reset, or both. The CUB's micro-circuits can accurately and silently accumulate enough counts in one hour to completely wear out an ordinary E.M. counter. More over, it can repeat this performance many times with just one set of batteries. Internal “micro-assembly" construction withstands many times the “g" force of shock and vibration compared to conventional construction. CUB counters also feature elastomeric contacts. This eliminates long term problems associated with contact corrosion. Battery operation, a high degree of input filtering, plus an inherent common mode rejection ratio of more than 120 dB @ 50/60 Hz, provides ultra-high immunity from electrical noise interference.
