Roller shutter controller STR-422 single-button, Un=24V AC, 8A, 1 module STR-422-24V

Roller shutter controller STR-422 – simple control of shutters and gates

The STR-422 controller is a device designed for convenient control of roller shutters, gates or other single-phase electric drives. Thanks to the possibility of working both as a standalone device and as an element of a central control system, it offers flexibility tailored to the needs of both installers and end users. The compact size (1 module) makes it easy to mount on a standard 35mm rail.

Functionality and application

The controller allows you to control roller shutters using momentary switches, such as doorbell buttons. Thanks to the built-in memory function, it remembers the set motor running time, allowing you to fully open and close the shutter with a single button press. The ability to stop the shutter at any position gives you additional control over its setting. LED signaling informs about the power supply status and the direction of movement of the shutter, which facilitates monitoring the operation of the device.

The STR-422 controller is particularly useful in installations requiring a reliable and easy-to-use roller shutter control system. The ability to connect multiple controllers in groups allows for central control of multiple shutters simultaneously, which is an ideal solution for residential and commercial buildings.

Construction features and safety

The controller housing is made of durable thermoplastic, which ensures its durability and resistance to mechanical damage. The device has a protection class of IP20, which means protection against touching with foreign objects with a diameter of more than 12.5 mm. The controller is halogen-free, which increases safety and minimizes the emission of harmful substances in the event of a fire. 24V AC power supply ensures safe operation of the device.
