{"product_id":"q-sys-qio-lvr4","title":"Q-SYS QIO-LVR4 Low-Voltage Relay Network I\/O Expander","description":"\u003cp\u003eThe QIO-LVR4 is designed for AV integrators and system designers who need to bridge Q-SYS networked control environments with legacy or non-networked control hardware. By providing four dry contact closure relay circuits over a Gigabit Q-LAN connection, it allows installed systems to trigger external devices such as room dividers, lighting controllers, projector screens, and door interlocks without requiring those devices to have native network connectivity.\u003c\/p\u003e\u003cp\u003eIts modular I\/O architecture keeps local wiring separate from core processing hardware, which simplifies physical installation and supports phased or scalable deployments in corporate AV, higher education, hospitality, and house-of-worship environments. PoE operation reduces cabling complexity by consolidating power and data onto a single Ethernet run, while Ethernet thru ports allow multiple units to be daisy-chained without additional network infrastructure. DC power daisy-chaining provides an alternative power path when PoE is not available.\u003c\/p\u003e\u003cp\u003eSetup is handled entirely within Q-SYS Designer Software v9.12, using a drag-and-drop workflow that reduces commissioning time compared to proprietary relay expanders that require separate configuration utilities. Surface and wall mounting hardware is included, and an optional rack kit accommodates half-rack, 1RU panel installations where needed.\u003c\/p\u003e","brand":"QSC, LLC","offers":[{"title":"Default Title","offer_id":52248827166904,"sku":"145114","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/145114_Q-SYS-QIO-LVR4-Low-Voltage-Relay-Network-I_O-Expander_ALT1sqr.jpg?v=1773852152","url":"https:\/\/soundpro.com\/products\/q-sys-qio-lvr4","provider":"SoundPro","version":"1.0","type":"link"}
