ABB REC650 1MRK008514-AA feature rich data network module

Customer benefits and savings 

• Risk Mitigation: Transfer of risk from client to ABB for coordinating design interface of all elements in the package to form a single product solution. 

• Reduced Client Resources: ABB being responsible for the scope of works described above reduces client manpower to engineer and manage the project. 

• Predictable Delivery & Cost Schedule: As a majority of the work is performed off site, 

the client is insulated from local labor shortages, environmental & industrial relations factors, granting fewer and shorter isolation possessions. 

• Reduced Site Resources: Comprehensive FAT can be performed before delivery reducing site commissioning requirements.

The ABB REG670 is a device for the protection, control and monitoring of generators and generator-transformer groups. 

It is suitable for all sizes from small to large generator sets. 

The REG670 has a comprehensive feature library to meet the needs of most generator applications. 

It has a large number of analog input channels and an extensive function library, 

allowing multiple functions to be integrated in a single device.

In a typical application, two units can provide full functionality and provide a high degree of redundancy.

The REG670 includes traditional 95% stator ground protection as well as 

injection-based 100% stator ground protection and third harmonic based protection. 

With injection-based protection, 100% of the stator windings can be protected in all operating modes, including star points. 

The third harmonic based 100% stator grounding protection uses the third harmonic differential voltage principle. 

The injection 100% stator ground protection can operate even when the generator is shut down.

The data communication properties include the following communication standards: SPA bus, LON bus, IEC 60870-5-103.

IEC 61850 via SPA-ZC 400. Profibus DPV1 via SPA-ZC 302. 

DNP 3.0 and Modbus communication with higher level equipment. 

Further, the LON communication together with the PLC functions minimizes the need for hardwiring between the feeder terminals.

ABB’s comprehensive service offering ensures life cycle support for medium voltage products 

ranging from installation and commissioning, through condition monitoring and plant maintanace programs, 

to decommissioning and recycling. 

Our global network of service centers and experts help customers to optimize the performance of 

their equipment without compromizing on reliablity and safetyDescription. 

ABB is dedicated to providing support through the entire product life cycle, 

from the pre-sales phase all the way to the engineering, commissioning and maintenance phases.

The ABB SupportLine service ensures that technical product support for all distribution protection and

control products is available from the product experts close to the customers world wide and

for a very wide range of product families.

Support over the product life cycle and beyond ABB provides technical product support for

products that are in active, restricted or legacy life cycle phases. 

The technical support for products in the legacy phase may diminish over time.

Products in the obsolete phase may still be technically supported.
