Hello everyone, I posted a few months ago regarding automating a dust collector and I have since re-designed my system and would like to get a little feedback before ordering all of the parts. This is my first time using a PLC. Plan: Have a Limit switch on each of the blastgates associated with my dust collector. When the blast gate is opened the limit switch signals the PLC which in turn signals a relay to turn on the dust collector. I also plan to create a "bin full " sensor with a couple of garage door sensors to turn off the machine when it gets full. The parts I planned on ordering are: C0-01DR-D - MICRO PLC, 8 DC IN / 6 RELAY OUT, W/ RETENTIVE MEMORY, REQ 24VDC POWER C0-01AC - 1.3AMP AC SYSTEM POWER SUPPLY NO POWER BUDGET DN-R35S1-2 - DIN RAIL, 35MM X 7.5MM X 1M, 2/PK AEM2G51Z11-3 - 1 N.O./1 N.C. limit switch - lever with 18mm nylon roller actuator 781-1C-12D - Cube relay 15A SPDT 12VDC coil w/ LED indicator & push to test button Does this look like everything I will need? Being my first install I am unsure how the limit switches get wired to the PLC. Do I need to purchase any of the ziplink cables? The PLC powers the switches themselves, correct? Any feedback would be greatly appreciated. Thanks!

You will need a programming cable for the Click, EA-MG-PGM-CBL and a socket for the relay.
The PLC does not provide power for the switches, they are expected to be powered by an external 24VDC source. This could be the C0-01AC, but I discourage powering anything from the PLC power supply due to possible noise and issues arising from shorting out the power supply.

Thanks for the quick response.
I will add a second power supply and a distribution block to my order.
There are so many different versions of the Click PLC, have I selected the best one for my application?

As long as you want relay outputs, that's a good PLC to buy.
You need:
A battery for retentive memory in the PLC
Hookup wire to connect everything
Power cord (and plug) to get power from the wall socket to the power supplies
A breaker to protect the power supplies
Switch to turn the whole thing on/off (if you need this at all). Maybe a lit switch so you can visually see that the control is ON
Enclosure. You probably don't want dust in the PLC.
Terminal blocks (DIN rail mount). Makes connecting remote sensors more straight forward. Not absolutely necessary

I would question your choice of a 12vdc coil relay, when you have either 120vac or 24vdc already available. Choose a relay and proper coil suppression for a power supply you already have. (I'm assuming this is the relay you will activate the dust collector motor with, and will be wired to the PLC output for activation)
