Roller shutter controller STR-421 two-button, Un=24V AC, 8A, 1 module STR-421-24V

Roller shutter control with time programming function

The STR-421 controller is a device designed for convenient control of roller shutters, gates or other devices powered by an electric motor. It operates at 24V AC and allows for handling a load of up to 8A (300W), making it a universal solution for both home installations and commercial facilities. The compact housing with a width of 1 module (18mm) allows for easy mounting on a standard 35mm rail.

The controller offers two control methods: local, using connected buttons, and central, allowing simultaneous control of multiple roller shutters. Thanks to the programmable on-time, you can precisely adjust the operation of the roller shutter to individual needs. The memory function allows you to save settings even after the power is disconnected. Made of thermoplastic material with a matte finish, it is resistant to mechanical damage and provides an aesthetic appearance.

Versatility and reliability for professionals and users

The STR-421 controller is not only a convenient solution for end users, but also a practical tool for installers. Simple mounting on a 35mm rail and intuitive operation make installation quick and trouble-free. The ability to connect controllers in groups facilitates the implementation of more complex roller shutter control systems in multi-family buildings or commercial facilities. Halogen-free materials used in production increase safety. The IP20 protection class provides protection against accidental contact and the ingress of solid objects larger than 12.5 mm.

• Two control methods: local (buttons) and central (group), providing flexibility in system configuration.
• Programmable on-time: allows precise adjustment of the roller shutter operation to the user's needs – from full opening/closing to stopping at a selected level.
• Memory function: remembers settings even after the power is disconnected, ensuring user comfort.
• Compact dimensions: 1 module (18mm) makes it easy to install in electrical distribution boards with limited space.
• Safety: halogen-free materials increase safety and minimize the risk of toxic gas formation in the event of a fire.
• Versatility: possibility of controlling not only roller shutters, but also gates and other devices powered by a single-phase alternating current electric motor.
• LED indication: a green LED indicates power, and red LEDs inform about the direction of the roller shutter movement – facilitates diagnostics and control of the device.

The STR-421 controller is characterized by a rated voltage of 24 V AC, a maximum load current of 8 A and a maximum switching power of 300 W. It is mounted on a 35 mm rail and has a width of 1 module (18 mm). The IP20 protection class provides basic protection against contact and the ingress of solids. The housing is made of thermoplastic material.

The STR-421 controller is a solid and reliable solution for anyone who values comfort and functionality in the field of roller shutter and other home automation control. Its versatility and ease of installation make it an ideal choice for both professionals and demanding end users.
