Somfy Isolation Relay TR2-U-E-230 for Two 230V AC Motors, Flush-Mounted 1822200

When a single wall switch must control two 230V AC tubular motors, connecting them directly can cause short circuits and motor damage. The Somfy TR2-U-E-230 isolation relay solves this by providing galvanic separation between the motors, allowing safe parallel operation from one control point.

Who is it for

Electricians and installers working on roller shutters, awnings, or screens where two motors need to be driven together. It fits standard flush-mounted boxes and works with existing momentary or latching switches.
