Allen-Bradley 1785-LT2 Line Transformer Module

Allen-Bradley 1785-LT2 Line Transformer Module is a Rockwell Automation PLC-5 era accessory cataloged as 1785-LT2. It belongs to the LT family of line transformer modules (LT1, LT2, LT3, LT4) and is used within PLC-5 backplane configurations to condition and couple line signals in automation systems. The LT2 module provides the transformer interface required by certain PLC-5 I/O arrangements, enabling reliable signal transfer in rugged industrial environments. LT-series line transformers are designed to be installed in a PLC-5 rack alongside other 1785-series modules, serving as the interface between the controller and external line circuits. For precise electrical ratings, pinouts, mounting guidance, and compatibility with specific PLC-5 models, consult the official Rockwell Automation literature and the current 1785-LT family documentation. As with other 1785-series accessories, installation and maintenance should follow Rockwell Automation guidelines and local electrical codes.
