The 1402-LS51 module is a line synchronisation module manufactured by Allen-Bradley/Rockwell Automation.

The Allen-Bradley 1402-LS51 Line Synchronisation Module is a solid-state module, not a hard-wired electromechanical module, which means it is suitable for a variety of industrial applications.

However, it should not be used for safety functions that require sudden surges of power, such as emergency stops.

Attempting to use this solid-state module for dcs-sis.com emergency functions may damage the module, cause it to fail, prevent the emergency or error it was designed to respond to, or cause injury to the user.

The purpose of the Allen-Bradley 1402-LS51 Line Synchronisation Module is to synchronise two different three-phase systems through features such as load sharing, automatic synchronisation, and high-speed power system monitoring.
