開關量采集模塊是一種信號采集設備，主要用來采集開關量信號，有些采集模塊帶控制輸出。模塊之間可以利用總線方式進行數據傳輸，接口通常是RS485，采集到的數據輸送到計算機中，或者將計算機輸送的指令進行相關狀態的控制，或者進行多個通信、或者遠程控制來實現某種狀態。而在采集和輸送數據或者指令控制狀態的過程中，它需要依靠標准的modbus協議或者定制的相關協議來執行。

開關量采集模塊具备独立性：开关量采集接口、开关控制输出接口和通信接口是隔离的，与系统之间是通过RS485传输也是隔离状态，这让其具有极强的独立性，不会受到其他系统的干扰。

開關量采集模塊

開關量采集模塊安全性高：由于模块都是低压工作的，采集接口独立并有过压保护功能，采集接口可以分为有源开关量，或无源开关量（属称干接点），每个输入接口都是独立的，在采集和控制的过程中抗干扰能力强。

開關量采集模塊拓展性好：数据通信和传输接口线路多采用RS485，可支持多个或多种不同模块的并联使用，能很好的实现拓展系统功能。数据通信协议采用modbus协议，可以很好的与其他协议兼容对接，使用方便灵活。

開關量采集模塊广泛应用于楼宇智控、工业总线、动力环境系统、安全监控、交通自动化等多个方面，发挥着总要作用。

The light breakfast was taken, and the adventurers moved on. At each step the way grew more and more difficult. Every mile was steeper than its predecessor, and in many instances it was rougher. The rarefaction of the air increased, and rendered the work of breathing more and more severe. The travellers panted like frightened deer, and their lungs seemed to gain little relief from the rest that the Doctor and his young friends were compelled to take at frequent intervals. The last of the huts of refuge was passed, and it seemed only a short distance to the summit. But it required more than an hour's effort to accomplish this final stage. The boys refused all offers of assistance, and struggled manfully on; but Doctor Branson was less confident of his powers, and was glad of the aid of the strong-limbed and strong-handed yamabooshees. All were glad enough to stand on the summit and gaze into the deep gulf of the crater, while their brows were cooled by the clear breezes from the Pacific. They were at the top of Fusiyama, 14,000 feet above the level of the ocean that lay so far below them, eighty miles from their starting-point at Yokohama, and their vision swept an area of the surface of the earth nearly two hundred miles in diameter. East and south lay the broad ocean. West and north was the wondrous land of Japan, a carpet of billowy green, roughened here and there with wooded hills and small mountains, indented with bays and with silver threads of rivers meandering through it. It was a picture of marvellous beauty which no pen can describe. "I should like to know what you make of them," said Lawrence. "Ah well, be you a Fleming?" We have now to see how, granting Epicurus his conception of painlessness as the supreme good, he proceeds to evolve from it a whole ethical, theological, and physical system. For reasons already mentioned, the ethical development must be studied first. We shall therefore begin with an analysis of the particular virtues. Temperance, as the great self-regarding duty, obviously takes precedence of the others. In dealing with this branch of his subject, there was nothing to prevent Epicurus from profiting by the labours of his predecessors, and more especially of the naturalistic school from Prodicus down. So far as moderation is concerned, there need be little difference between a theory of conduct based exclusively on the interests of the individual, and a theory which regards him chiefly as a portion of some larger whole. Accordingly, we find that our philosopher, in his praises of frugality, closely approximated to the Cynic and Stoic standards—so much so, indeed, that his expressions on the subject are repeatedly quoted by Seneca as the best that could be found. Perhaps the Roman moralist valued them less for their own sake than as being, to some extent, the admissions of an opponent. But, in truth, he was only reclaiming what the principles of his own sect had originally inspired. To be content with the barest necessaries was a part of that Nature-worship against which Greek humanism, with its hedonistic and idealistic offshoots, had begun by vigorously protesting. Hence many passages in Lucretius express exactly the same sentiments as those which are most characteristic of Latin literature at a time when it is completely dominated by Stoic influences. J. A. “I thought I saw—but it’s gone!” Larry retorted, lowering his voice also. “The Everdail Emeralds!” Larry repeated the phrase sharply. “Why, Jeff! I’ve read a newspaper story about them, in a Sunday supplement. That’s the matched set of thirty emeralds——” "You are not fit to go," Felipa said resignedly, "but that doesn't matter, of course." Dr. Arbuthnot, a great friend of Pope and Swift, was also one of the ablest prose writers, "The Memoirs of Martinus Scriblerus," published in Pope's and Swift's works, and the political satire of "John Bull," a masterly performance, being attributed to him. "Blank your Captain," roared the voice; "I'm no Captain." "What's that?" said the Deacon, rousing to interest, but carefully putting his thumb down to mark the place where he left off. "O, open it, Maria," groaned Si, "and you'll likely find his name writ somewhere inside." "I do not understand your one thing or your other thing;" answered Turner—"but I know this, that we have paid the tax, and that we will pay it no more—but as for touching what belongs to the London folks—I'll tell you what, if we do set fire to London, by St. Nicholas! if I see my own son Tom taking a penny's worth, I will fling him into the flames!"
