The ZKTeco AHEB-0808 Expansion Board is a high-performance I/O expansion module designed to extend the capabilities of AHSC-1000 and AHDU series controllers. Using OSDP V2.2 over RS-485 with AES128 encryption and an EAL6+ certified crypto chip, it ensures secure, reliable communication for critical access control and building automation applications.

Engineered for Advanced Security, the AHEB-0808 features 4 state-supervised inputs capable of detecting even minor resistance changes, providing robust protection against short-circuit attacks. Inputs can be configured as Active, Inactive, Short, or Open, with time zone management for precise control.

With 8 configurable relay ports (8 inputs / 8 outputs), the AHEB-0808 offers versatile deployment options in door control, alarm integration, and device automation. It supports universal 1224VDC power input, making it adaptable to a wide range of installations.

When paired with Armatura controllers, the AHEB-0808 enables large-scale scalabilitysupporting up to 388 inputs or 196 outputs on a single AHDU controller, and up to 12,801 inputs/outputs in combined systems. Integration with Armatura One security software provides full configuration, monitoring, and firmware updates via encrypted communication, with upcoming Cielo365 compatibility.
