Product Details

The 07KT98C GJR5253100R028 is enhanced integrated controller unit for ABB AC31 S90 PLC system.

This 07KT98C is upgraded variant of 07KT98 series, integrating CPU, digital and analog I/O channels in one compact housing, without additional base unit required. It complies with IEC61131‑3 international programming standard and supports multiple programming languages for industrial automation development.

It collects digital and analog signals from field sensors, executes cyclic logic scanning, and outputs control signals to drive field actuators. Built‑in high‑speed counter supports up to 50kHz pulse input for motion control scenarios.

Equipped with dual RS232 serial interfaces and CS31 system bus, it realizes data exchange with HMI, upper computer and remote I/O stations. Battery‑backed memory keeps key process data during power‑off.

Front‑panel LED indicators display power supply, running status, fault alarm and I/O channel status for fast on‑site troubleshooting.

Standard DIN‑rail installation, convenient for cabinet layout and equipment retrofit.

Widely used in legacy AC31 project renovation, power plant auxiliary control, manufacturing and process industry maintenance projects.

It is important spare hardware for PLC system overhaul, control program debugging and defective 07KT98C controller replacement.
