Applications - Metasys - Part No. 24-11064-00048 - DX-FAC-Adapter - Field Device

Important: The DX-ADPT- FAC4911 operates on BACnet/IP networks. It does not operate on BACnet MS/TP or N2 field bus networks. A site migration from N2 to a BACnet/IP network must be performed for the DX-ADPT- FAC4911 to operate.

The DX-ADPT- FAC4911 is a functional replacement for DX-9100-8454 Series Extended Digital Controller. The adapter comes with the FAC4911 Advanced Application Field Equipment Controllers and operate on BACnet/IP networks. It integrates into Johnson Controls® and third party systems. The DX-9100 series controller was very popular and was used primarily for central plant and air handling unit control. However, the controller's flexible programmability enabled it to be applied to a wide variety of equipment control applications, especially those requiring custom configurations. Also, its onboard real-time clock made it popular for stand-alone equipment control applications.

Note: The FAC4911 controller has a different dimensional footprint than the existing DX controller. The DX-ADPT- FAC4911 provides a solution for both physical mounting of the replacement FAC in an existing control panel, as well as the re-termination of the inputs and outputs in the same panel based on the location of the terminals on the FAC versus the terminal locations on the DX controller.
