Product Overview

Link IO is an Open Protocol, distributed IO System with a 5-year warranty designed to help our System Integrators access any project from small to large without compromising quality or flexibility.

Innon produces Link IO in collaboration with CAREL S.p.A, an Italian controls manufacturer trusted all over the world in critical control applications.

The Link IO contains one main unit which can be either Modbus or both Modbus and Bacnet with either RS458 or IP connection.

The system contains one main unit that can be either Bacnet or Modbus and up to 10 expansion units. 

This LNK-IO20-IP-BAC  is the main unit that comes with an IP connection and both BACnet and Modbus protocol available. 

This main unit has 20 I/Os, and you can expand it with 160 I/Os by using maximum 10 expansion units. So you get a total of 180 I/O points for one main unit.

This main unit has an IP connection to the controller and is using an RS485 connection to the expansion units.

To configure this main unit and the expansion modules, you can either:

1. Use our web configurator: https://link.innon.com.

Once you have downloaded your required configuration, you can upload it to your main unit. The expansion modules will be automatically configured. You can configure everything in one go.

2. Use the display of the main unit.

Another new feature is the screen which allows you to check the status of points or turn things on and off directly via the screen. This is ideal in projects where you need to turn the heating on, for example, before even commissioning the BMS.

Key Features:

  • 10 Universal Inputs or Outputs
  • 6 x Digital outputs (DO)
  • 2 x Digital Inputs (DI)
  • 2 x Analogue Outputs (AO)
  • Expandable up to 180 I/O points (up to 10 Expansion Modules)
  • Commissioning using the display
  • Hand/Off/Auto using the display
  • Watchdog for safe operation
  • Built-in stand-alone IO functions

Comfortable and Supportive, but Adjust the Filling
Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D

Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.
