Three-position relay with dual transmitter (roller shutter controller) with switch-mode power supply rH-TSR1S2i RH-TSR1S2I

Three-position relay for blinds – wireless control in your home

This three-position relay with a dual transmitter, also known as a blind controller rH-TSR1S2i, is a key element of the F&Home Radio wireless smart home system. It enables convenient and precise control of blinds, shutters and other two-way drives. The module is designed for both professional installers and end-users, offering easy installation and intuitive operation.

Versatility and functionality in a compact housing

rH-TSR1S2i combines the functions of a three-position relay and two independent contact inputs, allowing integration with existing control systems or adding new control points. Compact dimensions (48 x 48 x 22 mm) allow mounting in a standard installation box, ensuring a discreet appearance. The built-in pulse power supply eliminates the need for an external power supply, simplifying installation.

Precise control and reliable operation

The three-position relay allows setting the blind in three positions: open, closed and intermediate (half-open). Two contact inputs allow connecting two single-pole wall buttons, maintaining the traditional control method while integrating the blinds with the F&Home Radio system. Two-way radio communication (868 MHz) ensures a stable connection with the central unit, and a range of up to 100 meters in open space guarantees comfortable use. The built-in mechanical and logical blocking of the relay outputs protects against accidental activation of both directions simultaneously. The module also works in autonomous mode – physical buttons work even after losing connection with the server.

Application and compatibility

The rH-TSR1S2i module is ideal for new installations and modernization of existing blind control systems. It allows remote control via a mobile application, creating automation scenarios and operating physical buttons. It is compatible with other devices in the F&Home Radio system, creating a coherent and intelligent home ecosystem. The IP20 protection class ensures safe use in dry indoor environments.
