Description
Product Overview
The ABB 07KT98 GJR5253100R0260 is an integrated controller for the legacy Advant Controller 31 automation platform. Rather than relying exclusively on separate CPU and I/O modules, this basic unit combines program execution, digital signal handling, analog measurement and output functions, and communication interfaces in one assembly. It is suited to established machine-control and process-automation installations where the existing application and I/O architecture were designed around AC31 hardware.
The documented hardware includes 24 digital inputs, 16 transistor outputs, eight configurable digital I/O points, eight analog inputs, and four analog outputs. The analog inputs can be configured for supported voltage, current, and Pt100 sensor signals, while the analog outputs support specified voltage and current ranges. Exact signal configuration, channel grouping, and electrical limits must be checked in the relevant manual before connecting field devices. The unit also provides two serial interfaces and a CS31 system-bus interface for compatible system expansion.
For replacement work, the full order code matters. The 07KT98 family includes variants with different network interfaces, so a unit with a similar front panel or model-family designation may not have the same communications hardware. Confirm the installed controller’s order number, interface type, programming-software version, application backup, and battery condition before scheduling a changeout. A replacement may require transferring the original program and retained data, then checking I/O mapping and communication settings before returning the machine to service.
Because AC31 is a legacy platform, procurement should prioritize exact identification and test evidence over broad claims of compatibility. Ask for photographs of the actual label, confirm whether the unit is new or refurbished, and request documented functional testing where available.
Product Introduction
The ABB 07KT98 GJR5253100R0260 is a 24 V DC basic controller for the AC31 automation family, integrating digital and analog I/O with serial communication and CS31 bus support.
Before installing a replacement, confirm the network-interface variant, controller software compatibility, application backup, and battery condition. Check the signal configuration and output ratings against the existing field wiring.

Frequently Asked Questions
Q1. What is the ABB 07KT98 used for?
It is an integrated PLC/basic controller for ABB Advant Controller 31 systems, with onboard digital and analog I/O, serial interfaces, and CS31 bus connectivity.
Q2. What supply voltage does it require?
The documented supply is 24 V DC. Confirm the exact wiring and permitted supply tolerances in the manual before energizing the unit.
Q3. Does GJR5253100R0260 have Ethernet?
Do not assume it does. ABB lists Ethernet and ARCNET/CAN variants under different 07KT98 order codes. Match the complete order number and physical interface connectors to the existing installation.
Q4. Which programming software is required?
The 07KT98 is associated with ABB 907 AC 1131 programming software. The required software version depends on the controller’s interface configuration; verify it before making program changes.
Q5. Does replacing the controller require program transfer?
If the replacement does not contain the correct application and retained configuration, program and data restoration may be required. Back up the existing application and document I/O assignments and communications settings before removal.
Q6. What should be checked when buying a refurbished 07KT98?
Verify the full order code, interface variant, label condition, I/O functionality, serial communication, memory-card compatibility, and battery status. Request test records and warranty terms rather than relying on a visual inspection alone.
Q7. Can another 07KT98 variant be used as a direct replacement?
Not without a compatibility check. The family includes different interface versions. Confirm the installed network, software version, I/O requirements, and approved replacement code before substituting another variant.
