Information About VLCA-1688
The VLCA-1688 is part of the Alerton BACtalk Advanced VisualLogic controller family and is designed for systems requiring numerous interdependent control points. Its 16 universal inputs accept thermistors, 1000-ohm platinum RTDs, dry contacts, 0–10 VDC, and 4–20 mA signals, while selected inputs support pulse sensing. The controller provides BACnet/Ethernet, BACnet/IP, and BACnet MS/TP communication and can operate as a standalone controller using its battery-backed real-time clock. Its 12-bit A/D and D/A converters, nonvolatile flash memory, and programmable DDC functions support scheduling, trend logging, alarms, and advanced control calculations.
Key Features:
- BACnet Advanced Controller: Provides B-AAC functionality for programmable building automation applications.
- Universal Inputs: Includes 16 universal inputs with 12-bit resolution for multiple sensor and signal types.
- Binary Outputs: Provides 8 triac outputs rated at 24 VAC and 0.5 A.
- Analog Outputs: Includes 8 analog outputs configurable for 0–20 mA or 0–10 VDC operation.
- HOA Controls: Provides Hand-Off-Auto switches for manual binary output override and monitoring.
- Network Connectivity: Supports BACnet/Ethernet, BACnet/IP, and BACnet MS/TP communication.
- Processing: Uses a 32-bit processor with 4 MB flash memory for program and configuration storage.
- Real-Time Clock: Battery-backed clock supports schedules, trendlogs, and timed automation functions.
The VLCA-1688 delivers the reliability and precision required for programmable HVAC and building automation control.
