The Lowell RY-4A is a general purpose relay module built for systems integrators and installed AV professionals who need dependable multi-circuit switching in a compact, protected enclosure. With four fully independent DPDT relays, it handles a range of control tasks including source switching, muting, zone control, and auxiliary triggering without cross-interference between relay circuits.
Each relay activates via contact closure or voltage input across a wide 5-24V AC or DC range, making the RY-4A compatible with a broad selection of control systems and processors. Detachable Phoenix-style terminals simplify field wiring and future serviceability. The onboard test switch enables fast troubleshooting without external test equipment, reducing commissioning time on the job site.
The enclosed steel chassis protects internal components from dust and incidental contact in equipment rack environments. The permanently attached power supply accepts 100-250VAC input and provides a regulated 24VDC output, eliminating the need for a separate wall adapter or inline supply. For AV installers specifying relay control in commercial, educational, or house-of-worship systems, the RY-4A delivers proven Lowell construction in a self-contained format.
