Eaton RELAY-MS Mini-Slot Card for 5PX G2 and 9SX UPS Systems

Eaton DB9 RS-232 Relay/Serial Interface Mini-Slot Card for Eaton 5PX G2, 9SX, and 9PX Lithium-ion UPS Systems

The Eaton RELAY-MS Mini-Slot Card is a versatile remote power management solution designed for use with Eaton's 5PX G2, 9SX, and other compatible UPS systems. This easy-to-install card enables network monitoring and UPS control without requiring system shutdowns or restarts, ensuring seamless integration into your existing power infrastructure. Its dual-mode operation provides flexibility for different application needs, making it suitable for environments where reliable UPS communication is critical for protecting connected equipment.

In contact mode, the RELAY-MS offers dry contact relay outputs to transmit vital UPS status information such as load power, bypass status, battery conditions, and utility input status. This information can be utilized by alarm systems, programmable logic controllers (PLCs), or connected computers to trigger alerts or automated responses. The default contact mode allows for straightforward installation and operation, providing real-time status updates without complex configuration. The second mode, RS-232, facilitates direct serial communication with a computer or UPS control display unit via a DB9 connector (cable sold separately). This mode provides detailed UPS data for advanced monitoring and management, ideal for IT environments and data centers.

Designed with user convenience in mind, the Eaton RELAY-MS supports installation on Eaton 5PX G2 and 9SX UPS units without the need to power down or interrupt ongoing operations. Its compatibility spans a broad range of Eaton UPS models, including the 5P, 5PX, 5PX G2, 9PX, 9PXM, 9SX, and 93E series. The device communicates critical UPS information to alarm systems, PLCs, or computers, enabling proactive management and automated shutdown procedures in case of power anomalies. Additionally, the relay contacts can activate UPS shutdown functions based on external voltage levels or contact signals, further enhancing system protection.

Manufactured in China by Eaton Corporation, the RELAY-MS comes with a two-year limited warranty, ensuring reliable performance and support. Its straightforward installation process and flexible communication options make it an essential accessory for maintaining power integrity across various industrial, commercial, and data center applications.
