Remote control - The control board includes 2 remote controls. They offer strong anti-interference performance, sensitive control, and long-range operation, providing reliable and convenient wireless access to open and close the door body from a distance. External switch interface - When used as an internal board, an external switch can be connected to open and close the door body. This enables flexible wired control options and easy integration with local push buttons, sensors, or other control devices. Motor time - A built-in timer limits motor operation to 100 seconds to prevent the motor from running indefinitely after faults. This protects the motor, reduces wear, and enhances overall system safety and reliability. Safety design - The door can only move by pressing the button in the opposite direction when it reaches its travel limit, preventing abrupt or uncontrolled movement and reducing the risk of injury or damage. Use scenarios - Small cabinet, enclosure, or workshop door automation: Use the remote controls for convenient access from a distance while the external switch interface allows a local control point for manual operation or wired integration. - Residential or commercial doors with safety requirements: The 100-second motor timer protects against motor burnout in fault conditions, while the safety design prevents unwanted overrun during travel, enhancing occupant safety. - Office, showroom, or storage rooms requiring dual-control options: Combine wireless remote operation with a wired external switch for flexible control in various layouts and installation constraints.
