Model 10ACC-4 Four Channel Totalizer Card

provides the totalizer (counter) function, like the  Model 10ACT01 Counter/Timer input function for up to four individual TTL-level inputs (+ 5 VDC, maximum; contact closures are negative true to ground).  It is particularly useful in assembly-line applications that require the accurate counting of large numbers of parts.

Unlike the 10ACT01, the Model 10ACC-4 has input provisions for a user-supplied auxiliary external power supply from 9 to 15 VDC, which would let you keep the count "alive" during system power shut-down.
