Sainsmart iMatic v2

The SainSmart iMatic V2 provides 8 x 250V/AC 10A Relays channels that is controlled over ethernet TCP/IP.  This unit is extremely affordable, is powered via a local 12vdc supply and is also din mountable.  Other integrated solutions cost anywhere from 3 times to 10 times more.  This is by far the cheapest way to integrate relays into Control4.

This driver will only work on Control4 OS 2.6 and above.

Where can i purchase this unit?

This unit can be purchased from the Sainsmart website. Direct link below

Can i use more than one unit at the same time?

Unfortunately not.  Sainsmart have advised us that only one unit can be used on the same network at any time.

Why can't i trigger all the relays at once?

Due to limitations in the device we can only send 1 command at a time per request. Each request is sent immediately after we receive a reply. As such you may notice a slight popcorn effect (for aproximately 100 milliseconds from our tests) especially in devices such as blinds and lights.

I want to try this driver out before buying it?
All Chowmain drivers for Control4 come with a 7 day trial.
