Description
ABB GJR5253100R3262 07KT98
ABB GJR5253100R3262 07KT98 is a basic control unit in the ABB Advant Controller 31 series, belonging to the Advant Basic Controller of the Series 90 platform. It is the core controller of the ABB Procontic CS 31 intelligent distributed automation system and is also known as the ABB Advanced Control Processor Basic Unit. H4 indicates that the hardware version of the module is version 4.

This module has built-in digital input and output channels, and user programs are stored in EEPROM. It supports high-speed counting function, with a maximum counting frequency of 7kHz. The working voltage supports two specifications: 24V DC or 220V AC, which can be flexibly selected according to the on-site power supply conditions. The total weight of the machine is about 0.82 kilograms, produced in Sweden and certified by CE.
In the system architecture, 07KT98 communicates with remote I/O units through RS485 twisted pair bus, forming a distributed control architecture. The central unit is installed inside the control cabinet, and the I/O units can be installed nearby sensors and actuators. This decentralized layout can reduce wiring costs by up to about 80%. A single station can accommodate up to 192 binary signals and 96 analog signals, or any combination of the two. The communication distance can also be extended to 2 kilometers through the bus amplifier.
Communication capability is a prominent feature of this controller. It adopts ABB’s unique FBP (Fieldbus Plug) bus technology, and users do not need to change the communication interface hardware. They only need to replace different types of FBP bus adapters to freely switch between fieldbus protocols such as PROFIBUS DP, DeviceNet, Ethernet, ARCNET, CANopen, etc. All changes are automatically recognized and do not require special settings. The controller can accommodate up to 4 plug-in expansion communication modules and is equipped with two serial ports, which can be used for programming, ASCII communication, Modbus communication, or CS31 communication. In addition, 07KT98 can also operate as an ABB CS31 communication server, serving as a communication protocol server for Windows applications, supporting OPC and DDE interfaces, and complying with OPC Data Access Custom Interface Specification 2.04.
In terms of human-computer interaction, the module is equipped with a backlit LCD display screen and operation buttons, as well as an SD card slot for convenient program storage and data management.
In terms of local expansion, the CPU motherboard is equipped with local I/O expansion module interfaces, which can install up to 10 expansion modules, including various I/O expansion units such as digital I/O modules and analog modules. The input channels are divided into three groups, electrically isolated from each other, with 8 inputs in each group. The inputs use 24V signals from positive logic.
The programming tool is AC31GRAF (also known as 907 PC 331), which fully complies with the IEC 61131-3 standard and supports programming languages such as instruction lists, functional block diagrams, ladder diagrams, etc. It can also be programmed and debugged on-site through TCZ handheld terminals.
This product is widely used in industrial fields such as electricity, petroleum, mine hoisting, ports, heating, gas, water supply, sewage treatment, metallurgy, papermaking, etc. It is also a commonly used control module in KBA (Koenig&Bauer) printing machines, with the corresponding serial number KBA L0055965 in the KBA spare parts system. ABB has officially launched a modular retrofit solution for KT94 and KT98, which can directly replace the controller with an AC500 PLC and a pin compatible adapter, thus completing the control system upgrade without changing the original wiring of the printing machine.
It should be noted that the ABB Advant Controller 31 series (including 07KT98) has been officially marked as discontinued by ABB and replaced by the AC500 PLC platform. But this series still has a large number of equipment in use in global stock industrial systems and KBA printing machines.
