ABB DSDP140B 计数器板

DSDP140B计数是一种简单基本的运算。计数器就是实现这种运算的逻辑电路，计数器在数字系统中主要是对脉冲的个数进行计数，以实现测量、计数和控制的功能，同时兼有分频功能，计数器是由基本的计数单元和一些控制门所组成，计数单元则由一系列具有存储信息功能的各类触发器构成，这些触发器有RS触发器、T触发器、D触发器及JK触发器等。DSDP140B计数器在数字系统中应用广泛，如在电子计算机的控制器中对指令地址进行计数，以便顺序取出下一条指令，在运算器中作乘法、除法运算时记下加法、减法次数，又如在数字仪器中对脉冲的计数等等。计数器可以用来显示产品的工作状态，一般来说主要是用来表示产品已经完成了多少份的折页配页工作。DSDP140B它主要的指标在于计数器的位数，常见的有3位和4位的。很显然，3位数的计数器可以显示到999，4位数的可以显示到9999。

DSDP140B counting is a simple and basic operation. The counter is the logic circuit to achieve this operation, the counter in the digital system is mainly to count the number of pulses to achieve the function of measurement, counting and control, and at the same time have the function of frequency division, the counter is composed of the basic counting unit and some control doors, the counting unit is composed of a series of various types of triggers with the function of storing information, These triggers include RS triggers, T triggers, D triggers and JK triggers. DSDP140B counter is widely used in digital systems, such as counting the instruction address in the controller of the electronic computer in order to take out the next instruction in order, writing down the number of addition and subtraction when multiplying and dividing in the arithmetic machine, and counting the pulse in the digital instrument. The counter can be used to display the working status of the product, generally speaking, it is mainly used to indicate how many folding pages have been completed. DSDP140B its main indicator is the number of counter bits, common 3 and 4 bits. Obviously, a 3-digit counter can display 999 and a 4-digit counter can display 9999.
