ABB RED670 Intelligent Electronic Device

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.

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.
