That is the one sold by Massso for Masso controllers, and it is plug and play in that it has the connector and it is for the proper voltage - 24VDC. There are many other options that will work and are much less expensive, BUT…
- most run off 5VDC, and will need you to supply your own power for this (bypassing the power wire in their connector should it come with one)
- will require you to purchase and solder your own connector, which means you will need to be somewhat skilled at this, and have the time and understanding of the wiring diagrams
I purchased one I liked that had an additional ‘enable’ button on the side for safety, as well as no connector, which is what I wanted for my installation needs. At the time it was less than $70 CA with free shipping. It was 5V, which I wanted as I was connecting it to a 5VDC power supply in the control panel I built.
