You choose the kind of control action you want by installing jumpers on the terminal block
All 354 counters feature true plug-in design and are dust-tight from the front panel
The solid-state 354 is manufactured from a series of computer-tested plug-in circuit boards and assembled virtually without hand wiring. Because it has no moving parts in its logic circuits, its life expectancy is virtually unlimited. Even the load relay-the 354's only significant mechanical component-has a life expectancy of 100, 000, 000 operations (no load), while the optional solid-state switch module has a virtually unlimited life expectancy. As a result, the 354 achieves an overall reliability that surpasses even the high level achieved buy previous Shawnee counters. The Shawnee 354 operates on a digital logic circuit with three main elements: input circuits which allow it to count various types of DC pulses; a read-only-memory (ROM) whose out put is set by the counter's digital setting number wheels; and a comparator that continuously examines the outputs of the input circuit and ROM.
