Information About VLC-853-E
The VLC-853-E is part of the Alerton VisualLogic® family of native BACnet controllers developed for distributed direct digital control (DDC) applications. Built around a high-performance 32-bit processor, the controller executes control logic with fast response times while storing application programs and configuration data in nonvolatile Flash memory to preserve operation during power interruptions. As a fully programmable controller, it supports custom HVAC sequences for air handling units, central plant equipment, clean rooms, laboratory ventilation systems, terminal units, and other complex mechanical installations. Native BACnet MS/TP communication enables straightforward integration with Alerton Compass®, Envision, and other BACnet-compliant building automation systems without the need for protocol gateways.
Key Features:
- Native BACnet MS/TP controller: Communicates directly on BACnet networks at speeds up to 115.2 kbps.
- Eight universal inputs: Supports multiple sensor types including temperature, voltage, current, and dry-contact devices.
- Five hot-switching triac outputs: Controls floating actuators, relays, and other field devices.
- Three analog outputs: Provides proportional 0–10 VDC control for valves, dampers, and variable-speed equipment.
- High-speed 32-bit processor: Executes DDC control programs with approximately 100 ms logical loop time.
- Fully programmable logic: Allows field customization for virtually any HVAC control sequence.
- Nonvolatile Flash memory: Retains applications and configuration without battery backup.
- Downloadable firmware: Supports future software enhancements and feature updates.
- Backward compatibility: Integrates with existing Alerton VisualLogic installations.
- Wide humidity tolerance: Operates in environments from 0% to 95% non-condensing humidity.
- LED status indicators: Simplifies diagnostics, commissioning, and maintenance.
- Flexible HVAC applications: Suitable for central plants, air handlers, clean rooms, fume hoods, and large VAV systems.
The VLC-853-E delivers the reliability and precision required for advanced HVAC automation, distributed BACnet control, and intelligent building management systems.
