About the product

iSMA-B-AAC20-D controller is an advanced device to control building automation and HVAC systems with Dali Control. Use of SVM (Sedona Virtual Machine) allows you to finish the setup quickly and easily. It is ideal for smaller projects where you want to stay open protocol while keeping the development simple and the cost under budget. The controller has a DALI interface with built in power supply.

With the large number of inputs and outputs allows to integrate with other devices and sensors (AAC20 provides 8xUI, 4xDI, 4/6xAO and 4xDO). Its fast processor allows to control of even very large objects. Built-in RS485 can be used to expand number of I/O by connecting MINI or MIX series I/O modules using Modbus ASCII/RTU. In addition, to increase the versatility of the controller, it supports many open communications protocols like: BACnet, Modbus, SOX, DALI, M-Bus, 1-wire or oBIX (optional). AAC20 is mounted in a housing adapted for DIN rail mounting or directly on a panel. Separate, easy to remove connectors allow quick wiring without removing the entire module.

Demasiado pesado

No me gustó , además de ser muy complejo para armar , es demasiado pesado , es para paredes bien fuerte ya que requiere muchos tornillos

Great product if you know what you’re getting.

It’s a great product if you know some details before you purchase. Specifically, for how much it cost it’s a great product. After assembly it is sturdy and will hold anything you’ll be displaying on it within reason. Speaking of assembly, it’s straight forward and intuitive if you’ve assembled other things such as a basic end table. What you should know: it does not come with instructions. It’s not hard to figure out but if you’re someone that needs instructions this product isn’t for you. That being said, if you see what you bought it’s not hard to look at the picture and assemble it. It does not come with the shelves. If you can’t buy them premise or make them then this product is not for you. Lastly, and this part is important to me, not all the pieces are straight after assembly. I used a level to mount the product on the wall and make each shelve straight. However, due to the factory produced screw grooves it is not perfectly straight. If you need it perfectly level looking this product is not for you. Refer to my pictures and you’ll see how the left bar looks crooked even though I mounted it level in every way. However, it gives it a more rustic, modern farmhouse feel that we wanted. Otherwise, a great product. I am still very happy for what we paid for. I would recommend the product and buy it again.

Great product!

This is my second time purchasing these shelves. They are easy to set up, come with all the screws, brackets, and drywall anchors (if needed). I definitely love the quality, look and versatility. Being that my ceiling is slanted I couldn’t mount them from there but easily mount them to the surface beneath the shelving. My husband loved my idea and how they turned out! Highly recommend!
