12 actuators

Projects General Guidance
1

Hello, I'm working on an art project and want to run 12 actuators using arduino if feasible. The actuators are 24v and each draw 2 amps under full load. I have a 24v 12.5 amp power supply that I would like to power everything if possible, including the arduino.

Additional components I have accumulated for this project:
5-23V input / 5V, 3A continuous switching relay: http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=250842525572&ssPageName=ADME:L:OC:US:3160
Wireless 24 Volt DC Reverse Polarity DC Motor Control: http://www.gamainc.com/site/epage/130317_941.htm
3x 24V 4 Channel Relay Shield Module Expansion board For Arduino ARM PIC AVR DSP http://www.amazon.com/Channel-Shield-Module-Expansion-Arduino/dp/B009T1Z64G

I invision arduino extending 6 actuators at a time in intervals or until limit switches are hit to stay within my power supply constraints, by controlling them through the relay boards I have chosen above. The motor control would provide the polarity reversing. If anyone can help me with picking the arduino and additional componentry, by reviewing my component choices, pointers, reasons why this will fail, etc. all would be appreciated. Thanks in advance.

The UBEC makes sense to convert 24V to 5V to run the Arduino.

The three relay boards make sense to turn the 12 actuators on and off.

I don't quite see how you are going to use the remote-control. If you want to reverse all the actuators at once I would use a DPDT (Double Pole Double Throw) relay with contacts that can handle 24VDC/12A.

Thanks for the response! What arduino would you recommend for this project?

I do not need arduino to know what direction the actuators are going, simply that they all end up extending or retracting without blowing the power supply. I was planning to have the arduino hooked to the power supply through the UBEC, and then the relay boards hooked to the output of the remote control. Hope to be able to use the remote control - worked very good in a different project (range, etc).
