Function and Working Principle
The NKLM01-4 is used to carry communication signals between ABB Bailey control system modules.
In operation, one module sends control or data signals through the cable, and the receiving module interprets and processes those signals within the system. The cable is designed with shielding to reduce electrical noise and maintain stable communication, especially in industrial environments with high electromagnetic interference.
This ensures that connected modules inside the control cabinet can exchange information reliably and continuously, supporting stable system operation.
