SMI Simply Explained

The STANDARD MOTOR INTERFACE (SMI) is the standardized electrical interface for roller shutter and sunblind drives.

Well-known European manufacturers have collaborated to form the SMI working group and developed the digital motor interface. This standardized interface allows drives to be precisely controlled by switching commands and telegrams.

System features:

Depending on the application, up to 16 drives can be controlled electrically in parallel.
Controllers and drives are connected by a five-wire line with power supply and data transmission.
High-precision intermediate positioning
Query current motor positions
Motor feedback with diagnostic information
