what is the voltage required in plc?
399288
If you mean the programable logic controller...most plc's now required 24VDC to operate.

To measure ohms, DCV, ACV, Amps or what????

You didn't say what plc, servo, etc. but generally you get a servo control card for your PLC (sometimes called "axis module"), a servo amplifier, and a servo motor.\n\nYou place a desired position and some other parameters such as acceleration,deceleration in to registers in the PLC. The PLC card will then output a plus or minus 10 volt signal to the amplifier to move the motor. -10 volts is full speed reverse and +10 volts is full speed forward. +1 volt would be slow forward.  An encoder in the motor feeds back its position to the the servo card.\n\nThat's only one way. Several companies make stand-alone servo systems (intelligentactuator.com is one) that you either "teach" it a position or command a position and it does the rest.\n\nDepending on what you are doing, you project could be anywhere form easy to maddening.

The standard in Canada is 120v at 60Hz.\n\nHere is a table that lists many countries and their standard voltages:\n\nhttp://kropla.com/electric2.htm

I assume this is what you need  (look at page 2 of) :\nhttp://www.powerstream.com/Wire_Size.htm

The unit would be the volt: http://physics.nist.gov/cuu/Units/units.html

less than 0.3  for power sations\n0.5ohm for substation\n1 to 2 for homes

I've worked some with programming PLCs. e-mail me and maybe (it's been a long time) I can get you pointed in the right direction.

They are completely different as it was explained above. But other important difference is that a PLC could accept Analog Signals, Microcontroller is digital.

The following link has some information about PLCs as well as external links for additional information:\n\nhttp://www.htservices.com/Tools/PLC/index.htm

I still trying to figure out it's voltage, sorry. ;-) I try to look.  5.5x10 to the 14th power Hz   http://www.cs.williams.edu/~cs105/f01/text/ch3/DigitalTrans_14.html    Then scroll down until you find Prism.

Here's a link to the standard American Wire Guage table.  It has it all listed:\nhttp://www.eng.auburn.edu/~tdenney/ENGR1110/wireawg.html

Not sure. I use to be an electronics Tech but that was before SMPS existed. I'm guessing you might find something on the link below:

No matter what is the voltage rating, isolation or insulation is tested by using "MEGGER".\nThe value should be atleast above 1 Mega ohm in any case

We'd need to either see the circuit or have it described to us in order to answer.  If there are just two lamps and a voltage source and nothing else then the voltage across the second lamp would be 6V-2V= 4V\n\nSo 4V

WELL..IF YOU ARE GOING TO CHANGE A DISLEXIC TO ACCEPT ELECTRICITY OR A LIGHT BULB THEN YOU BETTER MAKE SURE EVERYTHING IS UP TO CODE...YOU WILL DEFINATELY NEED A 220 VOLT SERVICE CONNECTION..

Allen Bradley has PLC simulator software.  I believe it will simulate the usual SLC500 and micrologix line of PLCs.  As for a book, start at www.AB.com and check out their knowledge base.
