Industrial metal enclosure for reliable operation
Product Overview
The HBR-IO Elevator Floor I/O Module is designed to support elevator floor control in smart building access systems.
The module communicates with RFID access controllers through RS-485 Modbus protocol, enabling elevator floors to be controlled based on user access permissions. It provides 16 relay output channels, which can be configured as normally open (NO) or normally closed (NC) via jumper settings.
When integrated with access controllers and the building management platform developed by HomeScenario, the HBR-IO allows administrators to implement secure and flexible elevator floor access control for residential, commercial, and mixed-use buildings.
The module is typically installed inside elevator control cabinets and can be deployed with multiple units to support high-rise building requirements.
Key Features
16 Relay Output Channels
The module provides 16 independent relay outputs for controlling elevator floor access signals.
RS-485 / Modbus Communication
Uses reliable RS-485 Modbus-RTU protocol to communicate with RFID access controllers and elevator systems.
Flexible Relay Configuration
Each relay can be configured as normally open (NO) or normally closed (NC) using jumper settings.
Designed for Elevator Integration
Optimized for elevator floor control systems, allowing flexible floor access management.
Industrial Metal Enclosure
Installed in a durable metal box to ensure reliable operation within elevator control environments.
