The FX-PCA3613-0 is the controller used with the DX-PCA-Adapter and is a functional replacement for the DX-9100-8454 Series Extended Digital Controller. 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.
The FX-PCA3613-0 is capable of using either the N2 or the BACnet® MS/TP communication protocol. You must program the PCA3613 controller with the Controller Configuration Tool (CCT), which has similar, but not identical programming capabilities as the GX-9100. Use Release 10.1 of CCT and later to switch the field bus communications protocol in the PCA to either MS/TP or N2 communications protocol. Johnson Controls® replaced most N2 protocol products with MS/TP protocol products. MS/TP is the default communication protocol for all new controllers. Switchable communication protocols (performed in CCT) provide a cost-effective upgrade and modernization path for customers with existing N2 controllers. See the Modernization Guide for Legacy N2 Controllers - Facility Explorer (LIT-12012045) for controller-specific documentation with installation and commissioning support as well as tips for efficient and safe replacement.
