About the product

iSMA-B-AAC20-M controller (iSMA-B-AAC20) with M-Bus for up to 20 devices is an advanced device to control building automation and HVAC systems. 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 Mbus Interface allows you to pick up max 20 meters.

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.

    Great product
    Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
    Product is great with good coverage and ease of use. Much better than comparable products because it is very light feeling and doesn't leave a heavy or sticky residue on your skin. Perfect protection for anyone who burns easily or fair skinned. However I paid for the extra rushed 3 day shipping and it was delayed and I wasn't reimbursed the extra shipping charges even though it arrived 6 days later.

    Save your money- don’t buy
    Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
    Purchased this for our trip to Mexico. At two cruise ports we were doing a combination snorkel and pool day. I got this sunscreen because it was reef friendly and came with two bottles. Both bottles were IMPOSSIBLE to spray. You could not sunscreen yourself because you had to hold the bottle just right, push down with extreme force, and have your fingers place very specifically on the lid. My 13 year old and husband couldn’t even use the bottles. I did figure it out so I had to continually sunscreen everyone in the family. No one in my family has sensitive skin, but we all ended up with a fine rash after using this sunscreen. On days prior we used another brand and no one had a problem. We also reapplied often (every 60-90 min) and we still got pretty burnt. Maybe we got a bad batch…

    Good sunscreen
    This sunscreen works well, and has coconut oil base, which is good for your skin. The cans have an adequate amount in them, but I would also like to see something twice their size, if that's possible.

    Favorite Sunscreen
    My son suggested this to me and it has become my favorite sunscreen. I love the way it goes on when you apply it. Give it a try and you will see what I am talking about.

    Missing Expiration Date
    I've used this sunscreen for years, and all bottles have an expiration date on the bottom; these did not have an expiration date stamped anywhere.
