EtherCAT I/O system: IP 67 modules for extremely harsh environmental conditions
4/23/2014
Compact I/O modules in die-cast zinc housings
With the introduction of the new ER series, Beckhoff is extending the range of applications that can be served by the EtherCAT Box product line. These exceptionally robust ER series I/O modules in die-cast zinc housings are designed for particularly harsh environmental conditions, for example, in the heavy-duty and automotive industries as well as in robotics. Together with the EP and EQ module series, the EtherCAT Box I/O system covers a wide range of signals for all industrial applications and is intended for use outside of control cabinets.
Utilising die-cast zinc as the housing material, the IP 67 rated I/O modules from the ER series can be used in extremely harsh industrial and process environments. Fully die-cast, they are ideally suited to all applications where increased load capacity and durability are demanded. Typical application areas include heavy industry, for example, press lines and metal foundries, as well as in automotive environments where die-cast zinc is standard or for robotic applications that rely on resistance to weld spatter.
The new EtherCAT Box Modules are the ideal complement to the existing versions in plastic and stainless steel housings. The plastic EP variant is well-suited for use in wet, dirty or dusty environments in general mechanical engineering, in assembly technology and in semiconductor and logistics environments. Additionally, the EQ module series with full 慼ygienic design,' stainless steel housing and IP 69K protection is designed for applications in the food, chemical and pharmaceutical industries.
Die-cast zinc modules available for a wide range of signals
The ER series modules are fully compatible with the EP series and offer the same wide I/O selection: digital inputs with various filters, digital outputs with 0.5 A output current, and "combination modules" with freely configurable digital inputs or outputs. Moreover, analog input modules for current/voltage measurement are available. The range is supplemented by temperature measurement modules, serial interfaces, encoder inputs and motion modules.
The space-saving 30 mm modules and 60 mm wide modules are available in different channel variations. With a height of 126 mm and a depth of 26.5 mm, the ER series modules are extremely compact. Field devices and signals are connected to the modules via M8 or M12 connectors. The ER series provides an EtherCAT interface, a power supply connection and M8 plugs or sockets for signal forwarding. For high-current outputs there are modules with a 7/8" power supply and an M12 EtherCAT socket available. The EtherCAT Box Modules in the die-cast zinc version are qualified for an extended operating temperature range of -25 to +60 oC (storage temperature -40 to +85 oC).
The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
