The SRM-12 module roller shutter controller is designed for controlling window blinds or other devices powered by DC motors supplied with 12V or 24V voltage. The control can be operated locally or centrally by means of the reflector louvres. In the case of local control, double and single buttons can be used. In the case of central control, only double buttons can be used. In terms of functionality, the controller enables programming of two independent comfort settings (lower and upper) and the maximum time of roller shutter movement. SRM-12 can work as an independent controller or be combined into sections. The special functionality of the central control inputs makes it possible to lock the blind in a closed or open position. This enables cooperation with alarm systems and additional devices such as weather station, light intensity sensor, rain sensor, control clocks. Triggers from the "+" line are trigger signals.
