Information About VLC-853
The VLC-853 is part of the Alerton VisualLogic® BACtalk® controller family, engineered to provide reliable distributed control for commercial and industrial HVAC systems. As a native BACnet MS/TP controller, it communicates directly with BACnet supervisory systems while executing programmable control logic independently for uninterrupted equipment operation. Built around a high-speed 32-bit processor, the controller stores all application programs and configuration data in nonvolatile Flash memory, ensuring reliable operation even after power interruptions. The VLC-853 is commonly installed in air handling units, central plant equipment, VAV systems, clean rooms, laboratory ventilation systems, and other applications requiring accurate monitoring and control.
Key Features:
- Native BACnet MS/TP communication: Fully BACnet-compliant for direct integration into building automation systems.
- Eight universal inputs: Supports thermistors, dry contacts, voltage, and current input signals.
- Five binary triac outputs: Hot-switching outputs for controlling relays, dampers, valves, and other HVAC devices.
- Three analog outputs: Configurable 0–10 VDC outputs for proportional control applications.
- Fully programmable controller: Supports customized VisualLogic control strategies.
- Stand-alone operation: Continues executing programmed logic without continuous supervisory communication.
- High-speed processor: 32-bit architecture with approximately 100 ms internal logic loop.
- Nonvolatile Flash memory: Stores programs and operating data without battery backup.
- Downloadable firmware: Allows future software enhancements and feature updates.
- LED diagnostics: Provides operating and communication status indication.
- Industrial reliability: Designed for continuous operation in commercial building environments.
- Flexible HVAC applications: Suitable for air handlers, central plants, laboratory systems, and large terminal units.
The VLC-853 delivers the reliability and precision required for HVAC automation, BACnet building management, and programmable equipment control.
