Programmable Controller Designed for

Electro-pneumatic Systems

Summary this item is mainly the procedure which studies electricity system and in brief valid control

current of air to launch machine to compatibly flow the appearance of system.It of the fulfillment

part of system logic the controllers of the operation drive all procedure logic controller(PLC)

replace.PLC sensor and switch's aring an importation to carry, but launch the direct control valve of

machine is an exportation to carry and have an internal procedure to operate among them all circulate

essential logic, imitate other devices like calculator, in fixed time machine etc., carry on a control to

the whole movement appearance of system.p1EanqFDPw

Can according to need numerous time to establish and imitate thus of system, so all from PLC usage,

this item contains vivid advantage.Therefore can save time, the danger of decrease error, in the

meantime under the sistuation that use same material, it can be getting more precise.DXDiTa9E3d

Many company that is on the market used the PLC of normal regulations and it can not only control

with the current of air system, but also can use various electricity equipments.PLC wide range of

Aim at this kind of circumstance's a kind of viable way establish a controller that can provide

particular size and function.This kind of controller can create according to the tiny

controller.jLBHrnAILg

This kind of applies scope according to the tiny controller smaller, the machine that can used for a

type perhaps can use to do a be like the common PLC is similar and can be woven a distance of

controller, so it can pass variable turn of logic procedure to carry on various homework.All of these

characteristic basis concrete demand of dissimilarity but dissimilarity, concrete of design of empirical

of dissimilarity but dissimilarity.But the main advantage of this kind of design lie in designing a

personnel to understand an own controller very much, can freely control the big baby size of

controller, change it of function.This means that this item contains more special, but in the meantime

For a simple sport, the system auto procedure can complete, but for indirect or more complicated

sport, the procedure of system will produce complicated circuit and false signal.This is need another

method can save time, produce clear circuit, can keep accidental signal from hand over fold to stop

with circuit.Zzz6ZB2Ltk

The line roadbed method of different standard of this kind of way call follow the sequence and

advance gradually type or rule system, it to the current of air and the electricity system very valid, and

is also a foundation of this item.It include according to launch the system of foundation that the

machine appearance each dissimilarity variety establish.dvzfvkwMI1

The square one is each circuit that the step designs those kinds of standards.The second step is a

conjunction to receive to come from sensor and the switch sends the air or the fax to the supply line of

are systems, but the change of of two different appearances be called a step.EmxvxOtOco

The standard circuit which speaks of in times before can the in aid of design personnel define

different appearance different from what the variety of different step bring environment of system.The

end stage in design will have a sequence and explicit input and output which never changes to carry in
