HID Aero X1100 is an intelligent, IP-based 2-door, 4-reader access control controller that supports both Wiegand and OSDP protocols, offering expansion up to 64 readers and 388 outputs using HID Aero expansion modules like the X100, X200, and X300. It operates on 12–24 VDC and features AES-256 encryption, TLS 1.2, OSDP Secure Channel, and tamper protection, making it ideal for high-security applications. The X1100 includes 7 supervised inputs, 4 Form-C relay outputs, and supports integration with electromagnetic locks, card readers (HID Prox, iCLASS, Seos, MIFARE), REX devices, and door sensors. The X100 reader interface module extends two more readers, four outputs, and seven inputs and is used to scale up door control. HID provides several model variants such as ADC-AC-X1100-2PSE (standard 2-door controller), ADC-AC-X1100-4PSE (4-door kit with X100), and compatible expansion units. The system is fully compatible with access control software platforms like Alarm.com, HID's own SDKs, and third-party integrations. Ideal for government, commercial, and industrial access control, the HID Aero X1100 series is a future-ready solution that ensures secure, flexible, and scalable access management.
