Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756-SYNCH is an Allen-Bradley ControlLogix SynchLink communications module providing synchronous fiber-optic time synchronization and limited high-speed data broadcasting between distributed motion or drive control chassis. The module installs in any ControlLogix chassis slot and enables coordinated motion or data exchange across multiple chassis platforms in industrial automation systems. 1756-SYNCH supports networked synchronized control architectures requiring time alignment and cross-chassis data sharing.
