HID Aero™ X300
12-Relay Output Expansion Module with AES-256 Security
The HID Aero X300 delivers on-board IO support for up to twelve control points and four monitor points — pairing seamlessly with the X1100 intelligent controller for enterprise-grade access, elevator management, and custom automation rules.
Part No: X300A | VertX V300 Replacement
Product Overview
Scale Your Access Control with Intelligent Output Expansion
The HID Aero™ X300 is an output control interface module purpose-built for demanding enterprise environments. It extends the reach of the X1100 intelligent controller, giving security integrators a reliable, scalable path to managing dozens of physical outputs — from door strikes to elevator floors — under a single unified platform.
Built on HID Mercury technology, the backbone powering over 4 million panels installed globally since the early 1990s, the X300 delivers unmatched reliability. It is a direct form-and-fit replacement for the legacy VertX® V300, making upgrades straightforward without replacing existing enclosures or cabling.
- Controls up to 12 general-purpose relay outputs from a single module
- Chain multiple X300 units on a single X1100 for massive output expansion
- AES-256 encrypted communication between controller and IO modules
- Hardware crypto chips guard against key-theft and replay attacks
- Direct drop-in replacement for VertX V300 — no rewiring required
- DIN rail mountable using optional accessory bracket

Why Choose the X300
Key Features & Capabilities
Custom Rules Processing
Combine the X300 with the X1100's custom rules engine to build complex conditional logic — trigger outputs based on input states, time schedules, or security events without custom scripting.
Elevator Floor Control
Integrate natively with the X1100 elevator processing engine to restrict or grant floor-by-floor access for cardholders — ideal for multi-tenant buildings and high-security vertical transport.
AES-256 IO Encryption
All communication between the X1100 intelligent controller and X300 IO module is protected by AES-256 encryption, preventing eavesdropping and man-in-the-middle attacks on the RS-485 bus.
Hardware Crypto Chips
Dedicated cryptographic hardware protects stored keys and credentials against physical extraction and brute-force attacks, providing a robust hardware root of trust for every module.
7-Level Threat Management
Define up to seven discrete threat levels to instantly reconfigure access permissions across the entire facility — from routine operations through partial lockdown to full emergency isolation.
VertX V300 Replacement
The X300 is a certified form-and-fit replacement for the legacy VertX V300 module, preserving existing enclosures, mounting hardware, and field wiring while delivering modern security capabilities.
Open Architecture
Works with HID's broad ecosystem of certified software partners. Switch or upgrade management platforms over time without any hardware re-investment or re-certification, protecting your capital expenditure.
Comprehensive LED Indicators
Dedicated status LEDs for power, heartbeat, online/offline state, reader activity, input status, and relay state make field diagnostics fast and intuitive without additional test equipment.
DIN Rail Mountable
The X300 supports standard DIN rail installation via an optional accessory bracket, enabling clean panel-board integration alongside PLCs, power supplies, and other DIN-mounted equipment.
