The PD-Q series is a fivedigit, true subtracting electric predetermined counter that features pushbutton operation of both predetermined count settings and reset. The predetermined count is set by holding the reset button in and then depressing the easy to operate pushbutton selectors under each digit. The unit subtracts, one count for each contact closure or impulse and actuates a 4 ampere, 250 Vac switch when zero is reached. The pd-er series is identical to the PD-Q series, except that it has electric reset (ER) for remote operation, allowing either local or remote use.
