ABB DSDP140B 计数模板 DSDP140B计数器在数字系统中应用广泛

ABB  DSDP140B  脉冲计数板

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 the simplest and most basic operation. The counter is the logic circuit to realize this operation. Indigital system, the counter mainly counts the number of pulses to realize the functions of measurement, counting andcontrol, and also has the function of frequency division. The counter is composed of a basic counting unit and some controlgates, and the counting unit is composed of a series of various triggers with the function of storing information, such as RStrigger, T trigger, D trigger and JK trigger. DSDP140B counter is widely used in digital systems, such as counting instructionaddresses in the controller of electronic computers to fetch the next instruction in sequence, recording the times of additionand subtraction when multiplication and division are performed in arithmetic units, and counting pulses in digital instruments.The counter can be used to display the working status of the product, generally speaking, it is mainly used to indicate howmany copies of folding and collating have been completed. DSDP140B, its main index lies in the number of bits of the counter.There are three bits and four bits commonly used. Obviously, the maximum number of 3-digit counters can be displayed to 999,and the maximum number of 4-digit counters can be displayed to 9999.
