DECS-250 CGCM, Digital Excitation Control System

The DECS-250 CGCM controller is a system ready, total control and protection replacement package for the popular Allen-Bradley® 1407-CGCM (Combination Generator Control Module) package provided through Rockwell Automation Allen-Bradley®. This controller combines the latest technology and the proven reliability of the DECS-250 and Allen-Bradley® 1407-CGCM. The DECS-250 CGCM, when used in conjunction with an Allen-Bradley® ControlLogix&r control system, provides highly robust generator control, protection and system supervision.

Benefits

  • Emulation mode provides plug-and-play capabilities for quick and easy field replacement of existing Allen-Bradley® 1407-CGCMs.
  • Easy integration with the Allen-Bradley® ControlLogix® control systems.
  • Ability to Autotrack between legacy Allen-Bradley® 1407-CGCMs and DECS-250 CGCM reducing the need to update both control systems.
  • Powerful 15 A pulse width modulated power stage provides high initial response for exceptional system response to load transients.
  • Flexible PWM power stage makes it easily adaptable to any system - shunt, auxiliary winding, permanent magnet, or dc fed.
