Emerson A6824-R ModBus and Rack Interface Module
Emerson A6824-R ModBus and Rack Interface Module
INTRODUCTION
The ModBus and Rack Interface Module is designed for high reliability for the plant’s most critical rotating machinery. It reads parameters from all AMS 6500 modules and outputs these parameters via ModBus TCP/IP and/or ModBus RTU (serial). This 1-slot monitor is used together with other AMS 6500 monitors to build a complete API 670 machinery protection monitor. Applications include steam, gas, compressors and hydro turbo machinery.
Operators are provided machinery health parameters in the control environment for seamless integration. The module powers local graphical displays at the protection rack for machine and instrumentation readout. Either ModBus TCP/IP or ModBus RTU can be configured, or for redundant paths, can be used simultaneously.
SPECIFICTION
3U size, 1-slot plug-in module decreases cabinet space requirements in half from traditional 6U size cards
API 670 compliant, hot swappable module
Password protected user configuration
Self-checking facilities include monitoring hardware, power input, and hardware temperature
A6824 module can serve multiple 19” racks A6824 is a 6TE wide module, no redundant option, for use in the IMR6000 series, 19” rack
A6824R is a 4TE wide module, redundancy optional, for use in the IMR6500 series, 19” rack
