Hikvision DS-K2M002X 2 Door Access Control Expansion Module

The Hikvision DS-K2M002X is an access control expansion module designed to extend the capabilities of Hikvision access control systems by supporting control for up to two doors. The module communicates with the main access controller through an RS-485 interface, enabling reliable data transmission within the access control network. The unit supports connection to card readers using either RS-485 with OSDP protocol or the Wiegand interface, providing flexibility for integrating different reader types within a security system. This allows installers to deploy compatible access card readers, keypads or biometric readers depending on the project requirements. Designed for installation within electrical cabinets or control panels, the module supports standard DIN rail mounting, making it suitable for structured control panel installations used in commercial or industrial security environments. The DS-K2M002X also supports battery charging and discharging functions, helping maintain system operation during power interruptions when connected to backup power systems. LED indicators on the module provide clear visual feedback for power status, communication status, running status and door status, assisting technicians during installation and system maintenance.
