Kantech Us DU4-120V Pcb Controller Access Control

Product Description

The KANTECH US DU4-120V is a printed circuit board controller designed for access control applications managing multiple doors. It serves as the core logic unit in an access control system, processing credential data and controlling door hardware such as locks, readers, and request-to-exit devices. The DU4-120V operates at 120 volts and is intended for installation by licensed low-voltage or security system technicians in commercial and light industrial environments where centralized door management is required.

The DU4-120V is suited for multi-door access control deployments in commercial buildings, office suites, and secured facilities. It fits into panel-based access control architectures where a PCB controller coordinates credential verification and relay outputs for door hardware. Installers integrating this board into a larger access control system will find it appropriate for both new installations and system upgrades requiring a replacement controller board.

Key Features

• PCB controller format designed for multi-door access control system integration
• 120-volt AC input for compatibility with standard North American panel power configurations
• Sold as an individual unit for precise replacement or expansion purposes
• Designed for centralized door management in commercial access control panels

Compatibility

Designed as an OEM-style replacement or component controller for multiple-door access control panel systems. No specific compatible model numbers were provided in the available product data.

Installation Notes

Installation should be performed by a licensed low-voltage or electronic security technician familiar with access control panel wiring and NEC guidelines. Disconnect and lock out all power to the access control panel before handling or replacing the PCB controller. Avoid contact with board components to prevent electrostatic discharge damage; use proper ESD precautions during handling and installation. Verify system programming and credential database integrity after board replacement before returning the system to service.
