The Discharge Air Controller (DAC) (P/N 818-9001) is a packaged HVAC control board for use either as a standalone controller or in zone control applications using a Emerson E2 BX building control system. The DAC is capable of controlling heat and cool stages, fans, dehumidification devices, and economizers using on-board I/O and control algorithms, as well as monitor and interact with other building control systems and peripherals (such as smoke alarms and CO2 sensors).
The DAC supports local physical inputs and outputs and communicates with the E2 controller (version 3.00 and higher) via the RS-485 MODBUS network.
The E2 will support a maximum of 32 instances of the DAC to be added to a BX-300 or CX-300. The E2 will support a maximum of 50 DAC devices on a BX-400 or CX-400.
The DAC supports 15 relay outputs, 6 analog outputs, 10 analog inputs, and 20 digital inputs.
