back to home!!!

tah pe ak nk merepek kali nie.... nie la 1st post utk tahun baru.... hahahha.... 22 ari bln kot....bahahaha...

nk wat cmne 2bln gak la xsmpt nk post.....hahahaha.... mungkin agak sbok.... dkt2 akhir sem time 2.... byk la assgmnt byk la test2 last minute tp xpe...lh la tempoh.... pas2 bln 1 dh start exam.... mgu stdy week n mgu exam...lg la....bgun tdo kol 5.30 pas2 tdo kol 2....hahahaha......tp  dlm tahun bru nie byk mengajar ak tentang sesuatu yg bernilai utk di kongsi bersama........

tentang sahabat.... kdg2 sahabat ketika susah mmg susah nk dpt tp sahabat ketika sng........mmg sng nk dpt....

mule2 time knl baek je.... tp mungkin di sbbkn persekitaran yg lbh meluas and bru nk berkembang.......mule2 sem xlh nk pisah makan same ge mne2 same2.... tp disbbkn 1 bnd.... blh merubah segala2nye.....

dari zahir nye mungkin nmpk mereka baik sesama sndiri tp pd batin nye... mereka berperang sesama mereka....

sahabat yg dicari didunia kne la yg selalu nasihatkn kte yg selalu tegur kite.... dan sebagai sahabat sejati kite hendak la mendgr nasihat2 yg blh merubah kite..... bkn n jgn salah kn die kerana nasihatkn kite.....

setiap manusia mmmg byk kelemahan tp jika kite dgr nasihat yg diberi mungkin sikit demi sikit kte lh brubah....

fikiran kite kne la matang.... jgn la disbbkn bnd yg kite kejar xdpt pas2 kawan kite tinggalkn......2 trasa n kite...

ape yg trjd jdkn sebagai garis paduan supya kite lbh berhati2 memilih kwn.....post nie khas utk rakan U...

Dgree ???

Sedar atau pn x.... dh 2 minggu ak start klaz....YES!! ak meneruskn perjuangan ak sbg seorang mahasiswa pulak kali nie..... pada mulenye ak dpt thu keputusan rayuan 2 ak trus blank...hahaha.....igtkn xde rezeki.... rupa2nye ader  rezeki yg allah berikn nie ader pada setiap umatnye........ dgn riak wajah air muke mak ak yg ingin ak meneruskan perjuangan ak supaya dpt membela adik2 ku......  mule2 dpt mmg kelam kabut....hahaha
nk anta surat bnti keje la ape la medical la.......hahaha.... kpd rakan2 sekerja ak dri wsa... din, wadi, mad, n lain2.....ak mntk maaf la kalo ader wat pape salah.... sbb kdg2 ak ader terlebih kate ke.....hehehe....
kalo dulu diploma di kulim..... tp kini ku berjalan lg jauh ke utara kini ku di PERLIS.... bkn uum tp di UNIMAP..... kampus mmg bersepah2..... tp ok la....tiap jam ader bas yg pi tmpt yg cheq nk pi.....hehehe...

mmg mule2 fikiran agak terganggu.... cmne nk stdy la pela... tp xpe skunk cheq dh ok la.... tiap2 malam stdy bak kate taufik fikir cm sok final.....hehehe..... yes!! mmg agak susah... sbb permulaan bg ak.... harapan ayah n bonda ak yg ak pikul harus menjadi titik perubahan bg ak utk menjd seseorang yg lbh baik n pndi membawa diri.....  bonda ku berkata " kalo along xbelajar dri skunk nnt sape nk tolong adik2 yg kecik2 nie, supaya adik2 ader cth utk belajar lbh tinggi",...hurmm ye mama along ikut je.... yes!! mmg ak ader adik beradik smpi 5 org lg bawah ak.... lg kecik skli bru darjah 3......perjalanan mmg pnjang.... pada rakan2 ku doakn ak semoga diberi berkat setiap ilmu yg ak dpt..... hehehe..... totally mmg degree n diploma LAIN!! degree hurmmm ak masok2 je klaz 1st dh kuiz......cett.....hahaha..... cara pembelajaran mmg lain.... xsama n dip k.... ok thats its...

wHat iS PLC.....

Some of the people don't know what is PLC.. Only people who works at in industrial know about PLC..What is PLC.. plc is programmable logic 
controller.The PLC is usually seen in the machine..PLC give signal 
at the machine,and start the machine. supply in PLC is 24V/DC.
The programming in plc usually use is ladder diagram.Like or, and, load, 

BRAND


usually the famous brand in malaysia is siemens, omron,and keyence n etc. 

PROGRAM

POWER SUPPLY

An AC powered unregulated power supply usually uses a transformer to convert the voltage from the wall outlet (mains) to a different, nowadays usually lower, voltage. If it is used to produce DC, a rectifier is used to convert alternating voltage to a pulsating direct voltage, followed by a filter, comprising one or more capacitors, resistors, and sometimes inductors, to filter out (smooth) most of the pulsation. A small remaining unwanted alternating voltage component at mains or twice mains power frequency (depending upon whether half- or full-wave rectification is used)—ripple—is unavoidably superimposed on the direct output voltage.

For purposes such as charging batteries the ripple is not a problem, and the simplest unregulated mains-powered DC power supply circuit consists of a transformer driving a single diode in series with a resistor.      http://www.discovercircuits.com/P/pwr-actodc.htm

RELAY

A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits, repeating the signal coming in from one circuit and re-transmitting it to another. Relays were used extensively in telephone exchanges and early computers to perform logical operations.

A type of relay that can handle the high power required to directly drive an electric motor is called a contactor. Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called "protective relays".

WIRING DIAGRAM

How to Read Pneumatic Schematic Symbols....

The block  

• The block symbolizes the possible valve functions or positions. Example: A 5/2 valve schematic will be illustrated with 2 blocks describing two valve functions or positions. A 5/3 valve schematic will show three blocks describing 3 possible valve functions or positions.

        The Actuator

• Pneumatic valves can be operated in several ways. Hand operated ( including levers and push and or push pull buttons) ; Air piloted (Operated remotely by pneumatic signals); Solenoid (directly actuated with electronic signals)
• A is pressurized and B is exhausted
• B is pressurized and A is exhausted.

       The arrows

• The Arrow symbols illustrate the direction of gasses flowing into and out of the valve ports. Gas is pressure is supplied from port P. Depending on which of the valve blocks is in function, the gas is directed to port A or B as shown by the arrows.

        Exhaust Port 

• The inverted triangle symbol denotes an exhaust port. The letters EA indicate this is the exhaust port for the A circuit. Ebin turn indicates the exhaust port for the B circuit.  

       The Return spring

• The spring symbol defines the "at rest" position of the solenoid valve. The spring "Pushes" from the side it is drawn on and places the right side block diagram of the valve in function.

        The T Symbol

• This symbol indicates that a port is closed and is neither passing or exhausting gas.

        Pressure or Air supply symbol

• This symbol indicates the air supply port. In addition to this symbol the letter P or the number 1 also indicates the air supply port.
