Hi i'm new need help please with: unitary, modualr and rack PLC sytems.

Your intel device is not what you want. Its not a PLC, nor is it a device that can be controlled by a PLC output.

Here is a list of PLC input and output modules that can input data or control devices:

There are links to a spec sheet for each device.


If you want some devices that can be used by PLCs in control applications:

Here is a pressure transducer datasheet. It sends a 4-20 milliAmp current signal to the PLC that is proportional to the amount of pressure that it detects.

Here's a datasheet for a panel LED indicator light. A PLC output can turn this light on and off to indicate the status of something in a system.

Here's a datasheet for a digital meter that can connect to a PLC analog output. The PLC can transmit a voltage to the meter that's proportional to the value of some parameter to be displayed for a person to see.

Hi John

Apologies for my previous post. Yes, it was meant to be a joke, and yes, it was at your expense. Hang around here and grow a thick skin - we all have!

The problem that experienced readers at this forum have found is that we get many, many enquiries almost all phrased like yours. For example, do a search here (using the 'Search' link above) for the word 'unitary' - see how many questions there are of this nature, and how identical the responses are.

You have a problem in common with many other students. Your teachers/lecturers are using terminology like unitary etc which no-one in the real world uses to differentiate types of PLC. It's like saying "let's group all cars according to the colour of the illumination of the instruments on the dash." Well, yes you could do this, and there would be categories for white, red, blue, orange etc but no-one uses this! We can't influence what schools or colleges teach, and furthermore you're stuck with a genuine quandary. Do you give the teacher the answer he expects (which is irrelevant and wrong), or do you take advice here, give a much more credible and useful answer, and then get marked down for criticising the guy's question?

We're not very good here at doing homework assignments. What we are good at is identifying sources of information; answering short specific relevant questions; offering advice or assessments of homework that's been done or partly done; and above all, sharing and learning. There's no-one who knows it all and we all get to learn something.

Regards

Ken
