BACnet Application Specific F.C.U Controller

DSx1150B is a standalone BACnet B-ASC class programmable controller. It is designed for monitor and control fan coil unit or lighting devices.

Description

   DSx1150B is a standalone BACnet B-ASC class programmable controller. It is designed for monitor and control fan coil unit or lighting devices. It uses 32-bit microprocessor core, transmission rate up to 76,800 bps, transmission distance up to 1,200 meter. DSx1150B has 1 Binary Input (BI), 1 Analog Input (AI) and 5 Binary Output (BO).

In addition it has an MSnet port can connect to an external LCD control panel for user operation and control. Using a remote or local browser or a group control panel can perform all, group, or single unit control and monitoring functions such as temperature, fan speed, timer Off, schedule On/Off, etc, monitor temperature value, system operation status, fan speed status, run time accumulation, energy consumption, fault alarm, etc. DSx1150B conforms to international BACnet MS/TP communication protocol and fully compatible with any BACnet system.

Features
