The Grow K220 is a specialized control board that serves as the central processing unit for fingerprint-based authentication systems. It manages the communication with connected fingerprint reader modules, performs fingerprint template matching against its onboard database, and triggers the relay outputs upon a successful match. This design separates the sensing element from the control logic, allowing for flexible system configuration and robust performance.
Engineered for reliability in access control applications, the board operates on a broad DC input range, making it adaptable to 12V or 24V security system standards. The dual Form C (SPDT) relay outputs provide dry contact closures, allowing integration with a wide array of door strike mechanisms, electronic locks, or alarm panels without signal interference.
