07KT98 GJR5253100R0260 07 KT 98 | ABB | Advant Controller 31 Basic Unit

Product Description

The 07KT98 (GJR5253100R0260) is the base processing unit of the ABB Advant Controller 31, a compact programmable logic controller designed for the Advant OCS (Open Control System) platform. It provides integrated CPU, memory, and communication interfaces in a single module, supporting discrete and analog control tasks in small- to mid-scale industrial applications.

This basic unit serves as the central node for local I/O expansion and operator interaction via the OCS network. While not equipped with onboard I/O terminals, it connects to remote I/O modules over ABB’s proprietary fieldbus, enabling flexible system topologies in space-constrained environments.

FAQ
Q: Does this unit have built-in I/O?
A: No—the 07KT98 is a CPU-only basic unit. I/O must be added via compatible remote modules on the OCS bus.

Q: Can it be used outside an Advant OCS system?
A: Not directly. It relies on ABB’s proprietary OCS protocol and requires compatible engineering tools (e.g., Composer) for configuration.

Q: Is it still supported by ABB?
A: The Advant Controller 31 is a legacy product. While no longer in active production, ABB and third-party suppliers offer repair, refurbished units, and migration support.
