ABB GJR5253100R3160 Programmable Logic Controller

Basic Information

Model and Series: Model number GJR5253100R3160 belongs to 07KT98 series.

Place of origin: Germany.

Dimensions and weight: Measuring approximately 25.4 cm long, 10.2 cm wide and 15.2 cm high and weighing approximately 0.9 kg, its compact dimensions make it easy to install and use in a variety of industrial equipment or control cabinets.

Performance Features

Processor performance: With a high-efficiency processor, it can quickly handle a large number of logic operations and data processing tasks to ensure real-time response and stable operation of the system, which can meet the high-performance requirements of complex industrial control scenarios.

Storage capacity: has a certain capacity of programme memory and data memory, the specific capacity is not explicitly given, but enough to support the user to write a more complex control program, and store the relevant operating data and parameters, to facilitate the user to carry out flexible configuration and expansion according to different application requirements.

Communication capability: Supporting a variety of communication protocols and interfaces, such as Ethernet, RS-232, RS-485, etc., it can conveniently communicate with other devices for data communication and networking control, realising seamless connection with the host computer, touch screen, frequency converter, sensors, actuators and other devices, constructing distributed control system, and meeting the demand for integration of industrial automation system.

Functional characteristics

Input and output interfaces: Equipped with rich input and output interfaces, including digital input and output, analogue input and output, etc., it can be flexibly configured with different I/O modules to meet the signal acquisition and equipment control requirements of various industrial sites. It can connect all kinds of sensors, buttons, switches and other input devices, as well as motors, valves, relays and other output devices to achieve comprehensive monitoring and precise control of industrial sites.

Expandability: support for expansion modules, the user can be based on the actual application scenarios and control requirements, the flexibility to increase the number of I / O points, communication interfaces, special function modules, etc., to expand the system's functionality and scale, so that it can better adapt to the ever-changing production processes and control needs, improve the flexibility and expandability of the system.

Reliability and stability: the use of high-quality electronic components and advanced manufacturing processes, with good anti-interference capability and environmental adaptability, can be in a harsh industrial environment for a long time and stable operation, such as high temperature, high humidity, strong electromagnetic interference and other conditions, but also to ensure that the system's normal operation, and effectively reduce the system failure and downtime, improve production efficiency.

Programming flexibility: support for a variety of programming languages, such as ladder diagrams, function block diagrams, instruction lists, sequential function charts, etc., the user can choose the appropriate programming language according to their own programming habits and project requirements for the preparation of the control program, reducing the difficulty of programming, improve programming efficiency, but also to facilitate the maintenance and modification of the program.

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
