Product Overview

The DO-WG04 4 Door Network Access Controller with Metal Case Wide Voltage Power Supply Controller is a rugged, centralized access control board designed for industrial and commercial door management deployments. Manufactured by do rfid reader manufacturer, this TCP/IP networked controller provides full control for up to four doors, supporting Wiegand 26 and Wiegand 34 reader protocols. It is built for system integrators, security contractors, and distributors who require a stable, long-term supply of access control hardware for multi-door projects, office buildings, warehouses, factory floors, and institutional facilities.

This access controller addresses a core operational problem: how to centrally manage access across multiple entry points with reliable power supply, offline event buffering, and real-time network communication. The integrated metal case houses both the control board and a wide voltage backup power supply, eliminating the need for separate enclosure and power sourcing. This simplifies procurement for wholesalers and reduces installation complexity for project deployment teams.

Product Advantages

Centralized Multi-Door Control for Large-Scale Deployments
Unlike single-door controllers that multiply wiring and management overhead, the DO-WG04 controls four doors from one board. For distributors and system integrators managing projects with 20, 50, or 200 doors, this reduces controller count, simplifies cabinet wiring, and lowers per-door hardware cost. Bulk ordering a single SKU instead of multiple variants streamlines inventory management for wholesalers.

Integrated Wide Voltage Backup Power Supply
The controller ships with a built-in AC110-240V to DC9-16V / 5A power supply unit inside a metal case designed to also accommodate a 12V/7AH backup battery (optional accessory DO-400). This integration solves a common deployment problem: unreliable mains power causing door lock failures or data loss. For commercial facilities operating 24/7, this ensures continuous operation during power fluctuations or short outages, reducing on-site maintenance calls for installers.

Industrial-Grade Reliability for Continuous Operation
With an operating temperature range of -40°C to +70°C and humidity tolerance of 10–90% RH non-condensing, the DO-WG04 is suitable for uncontrolled environments such as factory gates, parking lot entries, cold storage facilities, and exterior building perimeters. The metal case provides physical protection against tampering and environmental dust, making it a preferred choice for industrial applications where plastic enclosures would degrade.

Offline Event Buffering for Network Resilience
The controller stores up to 100,000 transaction events in high-speed memory with power interruption protection. If the network drops, all card swipes, door openings, and alarm events are recorded locally and uploaded once connectivity is restored. For project contractors deploying access control in remote sites or buildings with unstable network infrastructure, this eliminates the risk of lost audit trail data.
