ABB GJR5251500R1101 S90 Communication Processor (07MK92)

ABB GJR5251500R1101 S90 Communication Processor (07MK92)

Basic Information

Model No. GJR5251500R1101 corresponds to serial No. 07MK92.

Place of origin: Sweden.

Weight: approx. 3kg.

Characteristics

Communication protocol support: as a communication processor, it supports a variety of communication protocols, can be freely defined through the programming and testing software 907MK92 communication protocols and transmission types, so that it can flexibly communicate with different devices and adapt to a variety of industrial automation control system requirements.

Data Processing Capability: With powerful data processing function, it can process and transmit a large amount of data efficiently, and can parse, convert and package data quickly and accurately to meet the requirements of complex data interaction in the industrial field.

Communication interface: It has 4 serial interfaces, which can be connected with AC31 basic unit through network interface, such as 07KR91R353, 07KT92 (index i and later), 07KT93 or 07KT94, etc., to realise the connection with Advant Controller 31 system, so as to build up a complete industrial automation communication network.

Application Areas

Industrial automation control system: Widely used in various industrial automation production lines, such as automotive manufacturing, machining and other fields, can achieve coordinated control and data sharing between robots, sensors, PLC and other equipment.

Process control system: In chemical, oil, natural gas and other process industries, it is used to connect process instrumentation and control equipment to ensure the safe, stable and efficient operation of the production process.

Energy management system: It can connect energy metering equipment and energy management platform to achieve accurate monitoring and analysis of energy usage, helping enterprises to optimise energy distribution strategies and reduce energy costs.

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
