The Eaton RELAY-MS is a dry-contact and serial interface management card designed for network engineers and IT procurement professionals. It provides a dedicated physical interface to enable automated shutdown and real-time network monitoring of compatible uninterruptible power supply (UPS) systems.
This networking card leverages an integrated DB9 port that functions dualistically across standard RS-232 serial communication and dry-contact relay modes.
The module is engineered for enterprise server environments, remote industrial control infrastructure, data center network closets, and edge deployment hubs. It is fully cross-compatible with mid-to-high capacity Eaton power architectures, specifically the 5P, 5PX, 5PX G2, 9SX, 9PX, 9PXM, and 93E equipment frames. It should NOT be deployed in installations that require active IP-addressable, SNMP, or web-based interface control protocols, which are instead served by distinct network management modules.
Dual-mode DB9 port provides dry-contact relay and serial interfaces.
Integrated Mini-Slot architecture eliminates need for external enclosures.
Triggers automated OS shutdown scripts during critical power failures.
Hot-swappable installation allows modular insertion without dropping loads.
Direct host system powering drops secondary power supply requirements.
