Alerton VLC-1188 Programmable Logic Controller

The Alerton VLC-1188 Programmable Logic Controller is a BACtalk field controller designed for central plant systems, including air handling units, clean rooms, fume hoods, and large terminal units, providing centralized, programmable control for HVAC equipment. This model is part of Alerton’s legacy BACtalk line and is listed as discontinued, with support tied to existing deployments. Retail and distributor data show the VLC-1188 with 11 inputs, 8 binary triac outputs, and 8 analog outputs, operating on a BACnet MS/TP network at up to 76.8 kbps for networked control of building systems. In practice, the VLC-1188 enables local logic and equipment coordination within a central plant, making it suitable for complex HVAC and process-control applications in commercial buildings.
