I researched about a dozen different PLC's and programmable relays. I finally decided on the Crouzet PLC's because they had the best combination of features I was looking for.
- Low cost
- Many inputs and outputs
- Easy to use programming GUI
- Powerful programming features
- Good tech support that is easy to reach by phone
Crouzet's web site has a complete list of all the different models of the Millenium 3 Programmable Logic Controllers
I chose a 12 vdc version for use with 12 vdc linear actuators. The model number of the PLC shown in our video is 88970045. You can't purchase directly from Crouzet/Schneider Electric, so you have to buy from one of their distributors. Allied Electronics is who I purchased from, but I had to call the local Allied sales office to order them since they did not have these PLC's on their web site. I also use Digikey as a good source for other electronic components, including the plastic box.
Firgelli Automaton is the company that I purchased the linear actuators from. Here again, I searched high and low for the best linear actuator. Price was the biggest deciding factor. I chose speed over force. In other words, you have to give up power in order to get higher speed of activation. The linear activator I chose runs at 2 inches/second with a max force of 28 lbs and has built-in limit switches.
