Review: It is good for quick and low-cost programmable project - 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. Review: Very happy - 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. ## Features - 8 digital inputs - 8 digital outputs - 3 andlog input - 8 optional DS18B20 digital temp, 1 optional humidity sensors - built-in I2C and SPI support, up to 1000 line PLC program ## Technical Specifications | Specification | Value | |---------------|-------| | Item Package Dimensions L x W x H | 5 x 4 x 1 inches | | Package Weight | 3 Ounces | | Item Dimensions LxWxH | 3 x 0.75 x 3.5 inches | | Item Weight | 3 Ounces | | Brand Name | CAI Networks | | Country of Origin | United States | | Warranty Description | 1 year | | Material | other | | Manufacturer | CAI Networks | | Part Number | WC8 | ## Images ![WebControl 8 Network IO Controller Programmable - Image 1](https://m.media-amazon.com/images/I/81nlFXASeNL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It is good for quick and low-cost programmable project *by H***S on August 7, 2024* I have been using many of them in the past 15 years.
