ABB 07KT98 GJR5253100R0260 Advant Controller 31 Basic Unit CPU Module

Product Description

The 07KT98 (GJR5253100R0260) is the central processing unit (CPU) for the ABB Advant Controller 31 (AC31) system. Specifically engineered for the Advant OCS (Open Control System) platform, this basic unit serves as the primary logic engine for small-to-mid-scale industrial automation. It integrates a high-speed real-time processor, non-volatile program memory, and specialized communication interfaces within a robust, compact enclosure designed for DIN-rail or panel mounting.

As a dedicated processing node, the 07KT98 (GJR5253100R0260) does not feature onboard I/O terminals, which maximizes its processing efficiency and minimizes heat generation. Instead, it coordinates system-wide operations by interfacing with remote I/O modules via ABB’s proprietary OCS fieldbus and CS31 system bus. This architecture allows the 07KT98 (GJR5253100R0260) to be deployed as a centralized controller in space-constrained cabinets, while inputs and outputs are distributed closer to the field devices in thermal power plants, water treatment skids, or manufacturing lines.
