ABB CCR 70 Repeater Module CCR 70 H&B Contronic

ABB CCR 70 Repeater Module CCR 70 H&B Contronic

Basic Information

Model No.: Model No. CCR 70 corresponds to part number P 72240-4-9450 670.

Dimensions and weight: dimensions approx. 20.3cm x 5.1cm x 30.5cm, weight approx. 0.6kg.

Place of origin: Germany and Malta.

Functionality

Signal relay and amplification: As repeater module, it is mainly responsible for relaying and amplifying the signal, enhancing the signal strength, extending the signal transmission distance, ensuring the reliable transmission of the signal in complex industrial environments, and ensuring the stable communication between various parts of the system.

Multiple communication mode support: support F net, coaxial cable 75 ohm, point-to-point communication and other communication modes, can be flexibly adapted to different industrial communication needs, to achieve efficient data interaction with other equipment.

System compatibility

The module belongs to ABB H&B Contronic series, also applies to ABB H&B Melody/Contronic S system, can be with the same series of modules such as AV, AW, EP, HA and other modules to build a complete industrial automation control system, to meet a variety of complex industrial control tasks.

Applications

Widely used in chemical, pharmaceutical, oil and gas and other process control industries, as well as power, metallurgy, water treatment and other industries, automation monitoring and control systems, effectively improve the stability and reliability of the system, to ensure efficient and stable operation of industrial production.

Service and Maintenance

• Only qualified personnel should carry out repairs. 

• The agreed warranty applies. 

• Before carrying out any cleaning or maintenance operations, disconnect the equipment from the electrical supply. 

• Clean the display and surrounding front cover with a soft cloth and mild detergent. 

• Replacing the battery incorrectly may result in explosion. Only use batteries recommended by the supplier. During the warranty period, the battery needs to be replaced by an authorized ABB service center

FEATURE

• Low-impedance busbar protection 

• Stub and T-zone protection 

• High functional reliability due to two independent measurement criteria: 

- stabilized differential current algorithm 

- directional current comparison algorithm 

• Phase-by-phase measurement 

• Reduced CT performance requirements 

• High through-fault stability even in case of  CT saturation 

• Full solid-state busbar replica 

• No switching of CT circuits 

• Only one hardware version for  

- 1 and 5 A rated currents 

- all auxiliary supply voltages between  48 V DC and 250 V DC 

- nominal frequencies of 50, 60 and  16.7 Hz 

• Short tripping times independent of the  plant’s size or configuration 

• Centralized layout: Installation of hardware  in one or several cubicles 

• Distributed layout: Bay units distributed  and, in the case of location close to the  feeders, with short connections to CTs, isolators, circuit breakers, etc. 

• Connections between bay units and central  unit by fiber-optic cables 

- maximum permissible length 1200 m  

- for distributed and centralized layout 

• fiber-optic connections mean interference proof data transfer even close to HV power  cables 

• Replacement of existing busbar protection  schemes can be accomplished without restrictions (centralized layout) in the case of  substation extensions e.g. by a mixture of  centralized and distributed layout 

• Easily extensible
