Subject to change without notice WWW.CYLON.COM page 1 of 3 DS0114 rev 61 DESCRIPTION The NEXUS is an IoT (Internet of Things) embedded ASPECT® Control Engine designed to provide flexible site control applications for medium to large scale building automation systems. It can be used to connect with Cylon CB Series and AAM NB Series of BACnet® MS/TP field level controllers. The NEXUS supports serial communications protocols such as BACnet®, AAM PUP, and Modbus®. Additionally, TCP/IP communications using FT/Net, BACnet®, Modbus® and Cylon’s Unitron (when used with the UC32.netK) protocols are available when using the RJ-45 connection. APPLICATION A capacity based licensing model makes the NEXUS family of controllers scalable for medium to large buildings applications, including a campus environment when combined with the ASPECT®-Enterprise server software. The NEXUS provides network management and integration of the supported field level RS-485 and TCP/IP communication protocols. When deployed with embedded ASPECT® Runtime Engine, the NEXUS is capable of supervisory-based control functions including but not limited to energy management routines, custom sequencing, alarm and event annunciation, historical alarming and trending, and master control scheduling. Additionally, streaming of live connected data is displayed rich HTML5 graphics using a web browser. ASPECT® uses secure web technologies to enrich the user experience through common internet applications for alarm annunciation and scheduling. Receive alarms either from the integrated alarm console or through e-mail clients, or Twitter®. Schedule your building equipment through an integrated scheduler or by using common scheduling platforms such as Microsoft® Outlook®, Apple iCal, Google Calendar™.

SPECIFICATIONS PHYSICAL Form Factor Fanless design Optimized for wall and DIN-rail mounting Designed for industrial conditions Dimensions 217 mm wide x 206 mm deep x 73 mm high (8.5 in x 8.1 in x 2.9 in) Weight 3.4 Kg IP Rating IP50 OPERATION Processor Intel® Atom™ E3827 1.75 GHz 2 cores Memory 4G (8x 256Mx16 DDR3L) 1333MHz Power Input Nominal input 24V AC / DC (18 – 26.4 V), 4.0 Amps* Also accepts standard Dell notebook AC adapter, 65 W, 7.4 mm plug* NEXUS requires a dedicated SELV 24 V 60 VA AC / DC supply* (Class II supply) or a dedicated SELV 19.5 V 65 W PSU*. For warranty purposes it is recommended that only the included PSU is used. A replacement can be purchased from ABB Cylon (see Ordering Information below right). If using a higher VA transformer, care must be taken to ensure that the voltage stays within specification. Earthing or Grounding of any of the terminals connected to the SELV power supply will cause serious damage to the power supply rectifier and will invalidate the product Warranty. Earth or Ground any of the terminals connected to this power supply. use this power supply to power CBXi, CBX CB, NB, or SBC control devices, or any other equipment, because it is possible that the other equipment may be connected to Earth or Ground.
