To control 230 VAC motors with reversing by switching the windings (similar to 3-point actuators for valves and dampers) we have a specialized module C-JC-0201B designed to control one louver and place it in the installation box near the shading element or directly in the louver body . Blocking of simultaneous switching of both outputs is blocked in this module both mechanically (internal arrangement of relay outputs) and programmatically (provided by the module's own firmware).
The module is equipped with two inputs, which are intended for connection of the button control of the blind. In the event of a communication failure, the autonomous function of the module is ensured - control of outputs (blinds) by buttons.

Notes:
-
The relay output is solved with mutual mechanical blocking of the switching of both outputs, when DO1u is switched on the motor goes up, when DO1d is switched on it goes down.
-
The relay contacts have a current of up to 16 A, so they can easily handle switching phenomena when closing and opening the contact.
-
Due to the power of the motors for driving the shielding elements, the power supply and control cable is fully suitable for a motor with a cross-section of 1.5 mm2.
-
Two inputs DI1 and DI2 are intended for direct connection of blind control buttons, in case of deep installation box (eg KOPOS KPR 68 or KPR 68 / L), or box with side space (eg KUH 1 or KUH 1 / L) we can fit module C-JC-0201B directly under the button controller.
-
In case of communication failure, the module automatically controls the outputs according to the status of inputs DI1 and DI2 (when DI1 is switched on, output DO1u closes, when DI2 is closed, output DO1d closes), simultaneous switching is blocked.
