Product Details

The 07KT98 GJR5253100R4278 is integrated basic controller unit for ABB AC31 S90 PLC system.

This compact all‑in‑one controller integrates CPU, multi‑channel digital and analog I/O inside single housing. It complies with IEC61131‑3 international programming standard and supports multiple programming languages for industrial automation project development.

It collects digital and analog signals from field sensors, executes cyclic logic program scanning, and outputs control signals to drive on‑site actuators. Dual built‑in high‑speed counters support up to 50kHz pulse input for motion‑related applications.

Equipped with Ethernet and serial Modbus interfaces, it realizes data interaction with upper computer, HMI and SCADA system. Battery‑backed memory preserves key process data during power‑off status.

Front‑panel LED indicators show power, run status, fault alarm and I/O channel status, convenient for on‑site inspection and troubleshooting.

Standard DIN‑rail installation simplifies cabinet layout and equipment retrofit work.

Widely applied 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 07KT98 controller replacement.
