## Description
Each relay channel consists of 2 output relays controlled by 2 GPIO pins. The component provides APIs to control these relay pairs while ensuring safe operation, particularly for driving bipolar motors. It prevents short-circuits by automatically managing direction changes with configurable inertia timing.
Each relay channel consists of 2 output relays controlled by 2 GPIO pins. The component provides APIs to control these relay pairs while ensuring safe operation, particularly for driving bipolar motors. To prevent mechanical strain on the motor, the component automatically manages direction changes with a configurable inertia delay, protecting it from abrupt reversals.
It also provides an optional tilting interface per channel base. Tilting makes a channel move with a specific pattern moving with small steps at a time. Tilting is specifically designed for controlling some types of curtains that need to be adjusted to let enter specific amount of day light.
Since it operates on relays, the switching frequency is limited to 10Hz which complies with the most of the general purpose relays' requirements. The minimum frequency is 2Hz and the duty cycle is about 10% in all ranges.
