Overview

The ABB NKSD01‑L10 DI Module Cable is part of ABB’s Symphony Harmony INFI 90 I/O product line. It is specifically designed for Sequence of Events (SOE) digital input modules, providing a robust and pre‑engineered connection between the SED (Sequence Event Detector) and the NTDI (Network Termination Digital Input).

This cable ensures accurate time‑stamped event recording, which is critical in power plants, process industries, and other automation systems where event logging and fault analysis are essential.

Technical Data

Typical Applications

• Power generation: Connects SOE digital input modules to termination units for turbine and excitation event logging.

• Process industries: Provides reliable event capture in chemical, oil & gas, and pharmaceutical plants.

• Water treatment facilities: Ensures accurate monitoring of pump and valve events.

• Manufacturing automation: Supports event detection in robotic systems and production lines.

• Infrastructure systems: Applied in building automation and utility monitoring networks.

Example: In a thermal power plant, the NKSD01‑L10 cable connects SOE modules to NTDI units, enabling operators to capture precise event sequences during system disturbances for troubleshooting and compliance reporting.
