The QIO-LVR4 extends a Q-SYS system with low-voltage relay connectivity for interoperability with non-networked control devices. Its modular network I/O approach helps separate local connections from processing hardware to support scalable system design.

It provides four dry contact closure relay circuits and supports PoE over a Gigabit Q-LAN connection. Ethernet daisy-chaining and local DC power daisy-chaining allow flexible deployment, while support in Q-SYS Designer Software v9.12 enables streamlined setup and management.
