First, determine the power terminal. 2. If a proximity switch or photoelectric switch is used, the brown wire of the switch (some are red) is connected to the instrument 12V (some are marked as VCC or U0), the blue wire is connected to the instrument GND (some are marked as COM), and the black wire is connected to the IN terminal (some are marked as CNT). If a two wire mechanical contact switch is used, the two wires should be connected to the IN and GND terminals above. Counting is the simplest and basic operation, and the counter is the logic circuit to realize this operation. In the digital system, the counter mainly counts the number of pulses to achieve the functions of measurement, counting and control, as well as frequency division. The counter is composed of basic counting unit and some control gates. The counting unit is composed of - series of flip-flop with the function of storing information, including RS flip-flop, T flip-flop, D flip-flop and JK flip-flop.Counter Relay CE website:http://www.cnecnko.com/relay/electrical-relays/counter-relays/
