Benefits

Microprocessor-based controller integrates a function-packed, easy-to-use feature set with a fully-configurable programmable logic controller to reduce installation costs by eliminating peripheral components and maximizing user flexibility to easily meet specific requirements.
Extremely rugged, potted design and industry-leading temperature, vibration, and shock specifications make the DGC-2020 optimal for harsh genset applications.
The Offline Simulator in BESTlogic™Plus helps identify and troubleshoot the logic without the expensive need for physical hardware.
NFPA-110 compliance with the RDP-110 (Remote Display Panel) simplifies emergency standby applications.
Low-line, single-phase, alternate-frequency override functions make it ideal for rental and reconfigurable genset applications. The DGC-2020 lowers user cost by automatically adjusting to typical rental and reconfigurable setups without additional costly switches or operator intervention, including genset protection level adjustment.
Integrated mains fail detection provides the user a cost effective alternative when selecting transfer switches.
Flexible programmable logic and programmable I/O make it easy to expand the DGC-2020's inputs and outputs with the CEM-2020 (Contact Expansion Module) and the AEM-2020 (Analog Expansion Module). You will save time and money by eliminating unnecessary external PLCs and control relaying.
Easy integration of the LSM-2020 (Load Share Module) to the DGC-2020 quickly adds additional functionality to the system for intuitive load sharing, demand control, genset sequencing, and Ethernet capabilities for a seamless paralleled system.
Intuitive BESTCOMSPlus® software simplifies setup with easy settings entry and simple drag-and-drop programmable logic, reducing the cost and commissioning time.
