LVDLA Controller v4 Digital Lock Access
Multi-door online access controller for wired electric locks & readers
DLA Controller v4 is the high-performance online access control unit that directly connects the WebLock Cloud with physical door hardware—including electric strikes, solenoid locks, turnstiles, and Wiegand RFID readers.
Engineered with integrated Ethernet, Wi-Fi, and NB-IoT cellular connectivity, each DLA v4 operates autonomously with offline intelligence for up to 50,000 credentials, executing cloud commands and access grants in under 200 milliseconds.
Key Capabilities of DLA v4
Engineered for reliability, security, and open interoperability in commercial real estate, hotels, and gated facilities.
MULTI-CONNECTIVITY
Integrated Ethernet 10/100, 2.4GHz Wi-Fi, and optional 4G LTE cellular backup for seamless cloud connectivity.
OFFLINE MODE
Stores up to 20,000 users and PIN codes in local non-volatile memory. Full functionality continues even during internet outages.
FET LOCK DRIVERS
2x solid-state FET lock drivers (peak 3A @ 12V DC each) for operating electric strikes, solenoid locks, and motorized access hardware.
WIEGAND INTERFACE
Standard Wiegand 26 / 34 / 66 bit inputs for connecting third-party RFID card readers, biometric scanners, and keypads.
3 Versatile Deployment Options
From single localized entrances to high-density server racks managing 40 doors per panel, DLA Controller v4 adapts to any building infrastructure with 12V DC architecture.
Compact Installation Box (Shield Hub)
Ideal when placing just one controller directly near the door, inside a ceiling plenum, or beside the door frame. Housed in the same standardized sleek ABS enclosure as the WebLock Shield Hub (188 × 65 × 23 mm) with optional battery backup.
- • 1 controller managing up to 2 doors
- • Standardized Shield Hub enclosure (188 × 65 × 23 mm)
- • Quick wall or ceiling mount near the access point
Power Enclosure with Battery Backup
Installed in central utility rooms inside a wall-mounted steel enclosure. Integrated with a regulated 12V DC power supply unit (PSU) and backup battery for continuous fail-safe power during blackouts. In standard enclosure you can fit up to 5 controllers.
- • Regulated 12V DC power supply unit (PSU)
- • 12V rechargeable backup battery for power outages
- • Tamper-protected lockable steel cabinet
High-Density 19" Rack Installation
19" rack panels mounted in standard server cabinets. Controllers feature custom snap-in holders that lock into the panel without mounting any screws. One rack panel houses 20 controllers for 40 doors.
- • 20 DLA v4 controllers = 40 doors per 19" panel
- • Tool-free snap-in clips — zero screws needed
- • Fits standard 12U, 24U, and 42U server racks
