SAGE 4400 RTUs


SAGE 4400

​The SAGE 4400 combines the best features of the SAGE 3030M and the SAGE 2400.  The 4400 is a rack mounted RTU with all the communications capabilities of the 3030M and the I/O flexibility of the SAGE 2400.  The 4400 uses the same I/O cards as the other SAGE products for maximum retrofit capability and is designed for applications that require a significant capability for discrete I/O. It includes enough processor power for integration of many IED’s as well as intelligent embedded applications and logic functions.

Each SAGE RTU provides the same browser-based user interface for easy configuration and setup. Each RTU offers IED integration, NERC CIP security, IEC 61131-based logic functions, communications protocols, and a custom applications library.​ [1]
