CAI Networks WebControl 8 Network IO Controller Programmable

I have been using many of them in the past 15 years. It is easy to use, work well, and get the job done. Unlike Raspberry Pi, it gets right to the point without fancy peripherals and other hassles. The only bad thing is the developer stopped updating it since 2018.

Totally cool what can I say. Using it with six Temp sensors and send changes to my ISY994. I also threw together a VB.NET app to pull data from it using get request and logging the temps. Did all that in 48 hours so that says a lot about how easy it is to use if you have the background. I am going to hook up a relay to trigger a low voltage strobe light at set points next. Not easy for a newbie to electronics though, but don't let keep you from learning and playing it.

A very reliable, easy to use and program network controller. I have been using these to control A/C and water heater in 4 different locations since 2013- they work great since then.

I have two of this PLC from CAI Networks (old version 2.2.2) and very happy with them. This new version is more interesting not only because of the new power supply which accepts a wide voltage range, but looks that the new processor is slight reliable and suffer less with EMI. For the price, this is by far a good choice for those who wants to automate something at home or even for small company applications. Just a breathing of my usage, here mine is linked to ISY from Universal Devices sending temperature parameters from several rooms, heater, boiler, pressure and power consumption. Also controls a water booster pump, the boiler heater backup and solar panel array daily angle. Plans are to expand control and create some redundancy on certain control parameters like heater.
