The Allen-Bradley 1756-SYNCH/A is a high-performance Time Synchronization Module for the ControlLogix platform. This module is essential for applications requiring precise, system-wide time stamping and event sequencing. By distributing Coordinated Universal Time (UTC) across the ControlLogix backplane, it ensures that all controllers and I/O modules in the system operate on a unified and accurate time base. The 1756-SYNCH/A typically works in conjunction with a GPS receiver module (like the 1756-GPS) or an IRIG-B time source to receive a precise time signal, making it ideal for industries such as power generation, process control, and manufacturing where data integrity and sequence of events are critical.
