433Mhz Rolling Code Receiver Controller This DC 12V/24V 1-channel relay receiver module works at 433Mhz and uses rolling code technology for enhanced security. It is designed to be compatible with Flors remote controls, providing a stable and reliable wireless RF switching solution for various automation applications. Wide Voltage Input: DC 12V / 24V Supports both DC 12V and DC 24V power supplies, making it suitable for different system environments and easier to integrate into existing installations such as gates, garage doors, barriers, and lighting control. 1-Channel Relay Output Equipped with a single relay output (1CH), the module can directly control one device or circuit, such as motors, lamps, locks, pumps, or other electrical loads within the relay's rated capacity. Rolling Code Security Adopts rolling code (hopping code) technology to generate a code with every transmission, effectively preventing code copying or unauthorized signal replay and improving overall security for access control systems. Compatible with Flors Remote Controls Specially designed to be compatible with Flors series wireless transmitters (433Mhz). This allows you to expand or upgrade existing Flors-based systems without changing the whole installation.
