Line Synchronization Module (1402-LS51)

The Allen-Bradley Line Synchronization Module (LSM) is a state of the art device that provides an integrated power generation control solution. The LSM is designed to meet the needs of manufacturers, system integrators, and sophisticated users of industrial and commercial alternators and co-generation systems that require two 3-phase systems to be synchronized with each other.

The PLC-5 based LSM provides a high-performance and cost-effective solution for the retrofit of existing power generation control equipment and for new installations. The module, through the use of multi-layered, multi-mode circuit boards and electronics, increases generator control performance, system speed, accuracy, and overall performance, while it reduces the complexity of conventional technology, integration time, cost, space, and hardware required.

Features The following is a list of LSM features:

• Synchronization — Simultaneous multi-channel A/D conversion, digital zero-cross detection, and numerically-generated contact closing windows yield accurate, precisely repeatable, breaker closure commands.
• Anti-Motoring Digital — control allows for the implementation of asymmetrical breaker closure windows. This feature provides module based anti-motoring protection.
• Load Sharing — A load sharing circuit is incorporated for use in multi-generator applications. The LSM regulates generator power output for optimal utilization of the total nameplate ratings.
• Power Monitoring — The LSM provides a full feature power monitoring solution. This information may be used for load control, protection, fault location, and line conditioning.
• Other Valuable Features
  • Installs in a 1771 I/O chassis for PLC-5 compatibility
  • Microprocessor controlled for fast response time
  • High accuracy for surgeless transfer
