Description: Rockwell Automation has introduced new Allen-Bradley XM 121 A Absolute Shaft and the XM 442 Voted Electronic Overspeed Detection System (EODS) relay modules that are added to Turbine Supervisory Instrumentation (TSI). The new modules are a scalable solution that can be easily integrated into a plant's control and information system. The following modules are the latest additions to the XM series: The XM - 121 A Absolute Shaft Module measures the turbine shaft's vibratory motion relative to free space, which is an important diagnostic metric on some large steam turbines. The modular and open design of XM machine condition monitoring and protection technology allows users to expand the XM-121 A system to include other modules or to easily link the device into a broader system. The new XM-442 Voted EODS Relay Module is the final piece in theAllen-Bradley XMEODS. The XM-442 provides four high power relays - three that serve as redundant shutdown relays, and one that serves as the alarm relay and redundant logic circuits that allow the XM-442 module to operate correctly even in the presence of a single internal circuit fault. As part of the Allen-Bradley EODS solution, the XM-442 Module helps with the reliability and redundancy necessary for performance, measurement and relay requirements of the American Petroleum Institute Standards 670 and 612 relative to over speed protection.
