Description
The EMX TRES-400-DEFENDER Access Controller Board is a genuine OEM 4-door TCP/IP access control controller PCB designed for professional vehicle and pedestrian access control systems. Supporting up to 20,000 users, 100,000 event records, and up to eight Wiegand readers (4 entry / 4 exit), this controller is ideal for commercial buildings, gated communities, industrial facilities, apartment complexes, and other high-traffic access control applications.
Designed for both online and offline operation, the Defender controller continues to process access events even during temporary network interruptions. Built-in TCP/IP networking allows real-time communication, remote management, and seamless integration into modern access control systems. Four programmable relay outputs provide independent control of up to four doors or gates, while Request-to-Exit (REX) inputs and door status monitoring offer flexible installation options.
This listing includes the controller board (PCB) only, making it the ideal replacement or component for custom access control panel installations. It is compatible with all standard 26-bit Wiegand readers, including card readers, keypads, and combination reader/keypad devices.
