Information About VLC-550-E
The VLC-550-E is a member of the Alerton VisualLogic® controller series, developed to provide distributed direct digital control (DDC) for commercial HVAC terminal units. Equipped with a powerful 32-bit processor, the controller executes control logic with a rapid 100 ms loop time while storing all application software and configuration data in nonvolatile Flash memory for dependable operation after power interruptions. Native BACnet MS/TP communication enables seamless integration into Alerton Compass®, Envision, and other BACnet-compliant building automation systems without additional protocol converters. The controller is optimized for fan coil units, heat pumps, unit ventilators, and similar HVAC equipment where precise temperature regulation, fan control, and energy efficiency are essential.
Key Features:
- Native BACnet MS/TP communication: Operates directly on BACnet networks at speeds up to 115.2 kbps.
- Fully programmable controller: Supports custom HVAC control sequences using Alerton VisualLogic™.
- High-performance processor: 32-bit architecture with approximately 100 ms internal logic loop.
- High-resolution universal inputs: 16-bit auto-configuring inputs support multiple sensor types.
- Multiple input compatibility: Supports thermistors, dry contacts, pulse inputs, 0–5 V, 0–10 V, and 4–20 mA signals.
- Nonvolatile Flash memory: Preserves applications and configuration without battery backup.
- Firmware upgrade capability: Downloadable operating code for future software enhancements.
- Intelligent wall sensor support: Compatible with Alerton Microtouch™, BACtalk® Microset™, Microset II®, and Microset 4®.
- Stand-alone operation: Continues controlling HVAC equipment independently if network communication is interrupted.
- Backward compatibility: Compatible with previous VLC-550 and VLC-550C3 installations.
- Fast diagnostics: LED indicators and programmable service functions simplify commissioning and maintenance.
- Optimized HVAC control: Ideal for fan coils, unit ventilators, heat pumps, and terminal unit applications.
The VLC-550-E delivers the reliability and precision required for intelligent terminal HVAC control, energy-efficient building automation, and BACnet-based facility management.
