Rockwell Automation recently announced a major product update, A key industrial automation component under its Allen-Bradley brand, the 1407-CGCM/C Combination Generator Control Module, will be discontinued and withdrawn from the market on December 31, 2023. This module is a programmable automatic generator controller that maintains the generator output voltage within a specific range by controlling the current applied to the generator field.

The 1407-CGCM/C module, with its single design, is capable of regulating both brushless permanent magnet exciter and brushless self-exciter motors, providing a variety of excitation control modes including automatic voltage regulation (AVR), manual or field current regulation (FCR), power factor (PF), reactive power (VAR), etc. In addition, the module also has functions such as soft start voltage accumulation, overexcitation and underexcitation limitation, low frequency compensation, line drop compensation, and supports automatic transfer to the standby CGCM unit in redundant systems.

For customers using this module, Rockwell Automation recommends evaluating and planning to migrate to other products or solutions as soon as possible. The company encourages users to remove references to the affected products and consider alternative products or engineering replacement options. In the meantime, Rockwell Automation will continue to provide technical documentation and necessary support to help users make a smooth transition.

The discontinuation of 1407-CGCM/C could have an impact on industrial users who rely on the module for power management and automation. As a result, businesses need to pay close attention to this change and contact Rockwell Automation’s customer support and maintenance team for more information on product replacement and migration strategies.
