Eaton RELAY-MS Relay Card-MS

The Eaton RELAY-MS Relay Card-MS is a remote management adapter that fits into a compatible Mini Slot on Eaton UPS units. It provides a single RS-232 management interface using a 9 pin D-Sub connector. This accessory enables automatic shutdown and network monitoring of the UPS system status for IT administrators.

Upgrading from basic USB

The card replaces simpler monitoring methods by adding a dedicated serial management link and network capabilities through the Mini Slot. The jump is worth it when you need automated graceful shutdown of connected servers and remote visibility of power conditions across the network. It is not for UPS models lacking a Mini Slot or for installations that require only basic USB signalling.
