Function and Working Principle
The NKSD01 cable is used to transmit digital input signals from field devices to SOE processing modules within the ABB Bailey control system.
In operation, field devices such as switches, sensors, or event detectors generate digital signals. These signals are transmitted through the NKSD01 cable to the SOE input module, where they are recorded and processed as time-stamped events.
The cable is designed with industrial shielding to reduce electromagnetic interference, ensuring that fast-changing signals are captured accurately without distortion or loss.
This allows the system to maintain precise event sequencing and reliable monitoring of industrial processes.
