Opus® XIO BACnet® Remote I/O

  • Product Description

    • The Opus® XIO series of BACnet® Remote I/O Modules are designed and optimized to expand the I/O points available to the Opus XCM family of Executive Controller Modules. When configured using Opus Supervisor, each XIO Remote I/O Module increases the available I/O point count of an Opus Executive by eight I/O points.
  • Application

    XIO Remote I/O Modules feature can control an assortment of HVAC and lighting applications as well as monitor any digital or analog point. All XIO Modules communicate via BACnet to Novar’s Opus BAS, enabling them to be easily integrated with other control functions.


    • BACnet MS/TP Communication protocol for easy integration
    • Universal inputs and Form C relay outputs interface with a wide variety of sensors and actuators
    • Available with HOA switches
    • Universal Inputs can also be used as Analog Outputs
    • Fused outputs reduce installation labor and panel space
    • 24V Power and BACnet communication expansion connectors minimize the need for daisy chain wiring in multi-module installations
  • Specifications

    DIN rail mount or panel mount in any orientation using four slotted screw holes
