Q-SYS Control I/O Expander

Q-SYS Control logo

The Q-SYS QIO-LVR4 expands your Q-SYS system’s capabilities to enable streamlined interoperability with non-networked control devices via low-voltage relay connectivity. By separating local I/O from processing hardware, the QIO Series offer modular and easily scalable network I/O to support your desired topology.

Features & Benefits

  • Native network low-voltage relay connectivity solution for Q-SYS
  • Four (4) contact closure relays (2-pin, 3.55 mm)
  • Power-over-Ethernet (PoE) capable
  • Daisy-chain up to four QIO expanders on a single network run (with local daisy-chained DC power)
  • Simple drag-and-drop integration and comprehensive management via Q-SYS Designer Software and Q-SYS Reflect
  • Surface- or rack-mountable (1RU, quarter-width)
  • Includes surface mounting hardware

Remarque: ce produit sera supporté dans le logiciel Q-SYS Designer version 9.12

  • Network control connectivity where you need it:
    The QIO-LVR4 allows you to provide your Q-SYS system with greater flexibility to deploy control connectivity where it’s most convenient. The QIO-LVR4 provides four (4) contact closure relays (2-pin, 3.5 mm) with transient voltage suppression to interface with third-party lighting systems, motorized shades, environmental systems, and more. Additionally, each of the QIO Series I/O expanders features a compact form factor that can be rack- or surface-mounted.
  • Expanded I/O customization:
    QIO Series is intended to present a simpler way to add network I/O connectivity to Q-SYS systems, decoupling the physical location of the I/O from processing hardware to support distributed or centralized processing architectures. Additionally, QIO Series lets you customize your I/O configuration, and compliments the strengths of newer Q-SYS Core models that were designed with fewer onboard I/O options (Core Nano, Core 8 Flex, or NV-32-H (Core Capable).
  • Simplicity & scalability:
    Daisy-chain up to four of the QIO Series devices on a single network run (with local daisy-chained DC power) to consume fewer network ports, avoid rack clutter, and allow for quicker future expansion without pulling additional network cables. Alternatively, QIO Series are also PoE-capable, providing simple single cable connectivity (when devices aren’t daisy-chained).
  • Designed for Q-SYS:
    The QIO Series deliver native network I/O customization to Q-SYS, a cloud-manageable audio, video, and control platform, built to deliver scalable, flexible AV solutions into the future.
