Information About VLC-550
The VLC-550 is a high-performance BACnet MS/TP controller that integrates directly into building automation networks while also supporting stand-alone operation. It features VisualLogic graphical programming with nonvolatile flash memory storage, allowing custom control logic and reliable long-term performance. The controller supports Alerton Microset and Microset II sensors for local interface functions, including setpoint adjustment, diagnostics and equipment configuration. With 5 inputs, 5 outputs, high-speed 100 msec logic loops, adjustable 10-bit analog inputs, LED status indicators and robust communication at up to 76.8 Kbps, the VLC-550 provides dependable HVAC control in a wide range of terminal-unit environments.
Key Features:
- BACnet MS/TP Compliance: Communicates on BACnet networks at speeds up to 76.8 Kbps for seamless BAS integration.
- VisualLogic Programming: Supports graphical logic development with nonvolatile flash memory backup.
- 5 Inputs / 5 Outputs: Provides flexible configuration for heat pumps, AC units and terminal-unit equipment.
- High-Speed Logic Loop: Executes internal control loops at 100 msec for responsive HVAC operation.
- Adjustable 10-Bit Analog Inputs: Configurable for thermistor, dry contact, 0–5 VDC or 4–20 mA signals.
- LED Status Indication: Includes per-output ON/OFF LEDs plus a communication-activity LED for diagnostics.
- Microset Sensor Support: Works with Microset and Microset II intelligent sensors for user interaction and setup.
- Stand-Alone or Networked Operation: Functions independently or as part of a BACnet-managed automation system.
The VLC-550 delivers the reliability and precision required for advanced HVAC terminal-unit control in building automation networks.
