Product Overview

• Part No: A6824R, 9199-00098-13
• Brand: EMERSON / EPRO

• Category: Modbus & Rack Interface Communication Module A6824R (9199-00098-13) is a 3U plug-in communication gateway module belonging to Emerson AMS6500 Classic machinery protection monitoring system, fully compliant with API 670 standard. As the core communication hub of the monitoring rack, it collects all measurement data, status information and alarm signals from vibration, thrust, expansion, overspeed and other monitor modules inside the rack. It converts internal rack bus data into standard Modbus TCP/IP Ethernet and Modbus RTU RS485 signals, realizing seamless data exchange with DeltaV, Ovation and other DCS, SCADA systems and upper monitoring platforms. The R version supports redundant deployment, improves system communication reliability, and adopts compact 4TE width design to save rack slot resources. It supports password-protected parameter configuration, front panel LED indicators display network link and module running status. Hot-swap design allows online replacement without interrupting the protection function of the whole rack. Widely used as maintenance spare part for turbomachinery protection systems in power, petrochemical and oil & gas industries.
