They are called ladder diagrams because they resemble a ladder, with two vertical rails supply power and as many rungs horizontal lines as there are control circuits to represent. If we wanted to draw a simple ladder diagram showing a lamp that is controlled by a hand switch, it would look like this The L1 and L2 designations refer to the two poles of a 1. VAC supply, unless otherwise noted. L1 is the hot conductor, and L2 is the grounded neutral conductor. The Sun And The Moon The Bravery Zip here. These designations have nothing to do with inductors, just to make things confusing. The actual transformer or generator supplying power to this circuit is omitted for simplicity. In reality, the circuit looks something like this Typically in industrial relay logic circuits, but not always, the operating voltage for the switch contacts and relay coils will be 1. AC. Lower voltage AC and even DC systems are sometimes built and documented according to ladder diagrams So long as the switch contacts and relay coils are all adequately rated, it really doesnt matter what level of voltage is chosen for the system to operate with. Note the number 1 on the wire between the switch and the lamp. The Idea Behind Circle Dock.

In the real world, that wire would be labeled with that number, using heat shrink or adhesive tags, wherever it was convenient to identify. Wires leading to the switch would be labeled L1 and 1, respectively. Wires leading to the lamp would be labeled 1 and L2, respectively. These wire numbers make assembly and maintenance very easy. Each conductor has its own unique wire number for the control system that its used in. Wire numbers do not change at any junction or node, even if wire size, color, or length changes going into or out of a connection point. Of course, it is preferable to maintain consistent wire colors, but this is not always practical. What matters is that any one, electrically continuous point in a control circuit possesses the same wire number. Take this circuit section, for example, with wire 2. In ladder diagrams, the load device lamp, relay coil, solenoid coil, etc. While it doesnt matter electrically where the relay coil is located within the rung, it does matter which end of the ladders power supply is grounded, for reliable operation. March 11, 2014 Over the course of the past year, many writers have offered their perspectives on Ubers dynamic pricing strategy. Perhaps the only consistency is. Take for instance this circuit Here, the lamp load is located on the right hand side of the rung, and so is the ground connection for the power source. This is no accident or coincidence rather, it is a purposeful element of good design practice. Suppose that wire 1 were to accidently come in contact with ground, the insulation of that wire having been rubbed off so that the bare conductor came in contact with grounded, metal conduit. Our circuit would now function like this With both sides of the lamp connected to ground, the lamp will be shorted out and unable to receive power to light up. If the switch were to close, there would be a short circuit, immediately blowing the fuse. However, consider what would happen to the circuit with the same fault wire 1 coming in contact with ground, except this time well swap the positions of switch and fuse L2 is still grounded This time the accidental grounding of wire 1 will force power to the lamp while the switch will have no effect. It is much safer to have a system that blows a fuse in the event of a ground fault than to have a system that uncontrollably energizes lamps, relays, or solenoids in the event of the same fault. For this reason, the loads must always be located nearest the grounded power conductor in the ladder diagram.

REVIEW Ladder diagrams sometimes called ladder logic are a type of electrical notation and symbology frequently used to illustrate how electromechanical switches and relays are interconnected. The two vertical lines are called rails and attach to opposite poles of a power supply, usually 1. AC. L1 designates the hot AC wire and L2 the neutral grounded conductor. Horizontal lines in a ladder diagram are called rungs, each one representing a unique parallel circuit branch between the poles of the power supply. Typically, wires in control systems are marked with numbers andor letters for identification. The rule is, all permanently connected electrically common points must bear the same label. Digital logic functions. We can construct simply logic functions for our hypothetical lamp circuit, using multiple contacts, and document these circuits quite easily and understandably with additional rungs to our original ladder. Pure Love Anthems Zip. If we use standard binary notation for the status of the switches and lamp 0 for not actuated or de energized 1 for actuated or energized, a truth table can be made to show how the logic works Now, the lamp will come on if either contact A or contact B is actuated, because all it takes for the lamp to be energized is to have at least one path for current from wire L1 to wire 1. Paltalk Sniffer more. What we have is a simple OR logic function, implemented with nothing more than contacts and a lamp. We can mimic the AND logic function by wiring the two contacts in series instead of parallel Now, the lamp energizes only if contact A and contact B are simultaneously actuated. A path exists for current from wire L1 to the lamp wire 2 if and only if both switch contacts are closed. The logical inversion, or NOT, function can be performed on a contact input simply by using a normally closed contact instead of a normally open contact Now, the lamp energizes if the contact is not actuated, and de energizes when the contact is actuated. If we take our OR function and invert each input through the use of normally closed contacts, we will end up with a NAND function. In a special branch of mathematics known as Boolean algebra, this effect of gate function identity changing with the inversion of input signals is described by De. Morgans Theorem, a subject to be explored in more detail in a later chapter. The lamp will be energized if either contact is unactuated. It will go out only if both contacts are actuated simultaneously. Likewise, if we take our AND function and invert each input through the use of normally closed contacts, we will end up with a NOR function A pattern quickly reveals itself when ladder circuits are compared with their logic gate counterparts Parallel contacts are equivalent to an OR gate. Series contacts are equivalent to an AND gate. Normally closed contacts are equivalent to a NOT gate inverter. We can build combinational logic functions by grouping contacts in series parallel arrangements, as well. In the following example, we have an Exclusive OR function built from a combination of AND, OR, and inverter NOT gates The top rung NC contact A in series with NO contact B is the equivalent of the top NOTAND gate combination. The bottom rung NO contact A in series with NC contact B is the equivalent of the bottom NOTAND gate combination. The parallel connection between the two rungs at wire number 2 forms the equivalent of the OR gate, in allowing either rung 1 or rung 2 to energize the lamp. To make the Exclusive OR function, we had to use two contacts per input one for direct input and the other for inverted input. Alice Tell Stories. Build Games. Learn to Program.
