CyberPower RELAYIO500 DB9 Contact Closure Module | Remote Management

Extend remote management control with a compact DB9 contact-closure module designed for infrastructure environments that depend on discrete signaling. With 5 outputs and 1 input, it gives integrators a straightforward way to trigger, monitor, and coordinate external equipment without adding unnecessary complexity. This is the kind of accessory that belongs in serious deployments: simple to wire, easy to integrate, and built to support repeatable control logic across server rooms, AV racks, and managed enclosures. The DB9 connection keeps compatibility familiar for teams standardizing on serial-style control paths, while the 3-year warranty adds confidence for long-term use. For procurement teams, the value is in reducing integration friction. For operations teams, it is in having a dependable interface for contact-closure signaling where uptime and predictability matter more than feature bloat. Use it when you need direct control, not another layer of software abstraction.
