Convenient installation: Standardized interfaces and pre assembly design make the installation process simple and convenient. Technicians can quickly connect it to the corresponding equipment and modules, reducing installation and debugging time and improving work efficiency. At the same time, clear labeling and reasonable wiring design on the cables also facilitate later maintenance and troubleshooting.

Working principle

When the ABB 3HAC7681-1 wiring harness is in operation, power transmission and signal transmission are achieved through the conductive core wires of the internal cables. For power transmission, current is transmitted from the power source to the electrical equipment through conductive core wires, providing the energy required for the equipment to operate; In terms of signal transmission, various types of electrical signals (such as digital signals and analog signals) are transmitted in the form of current or voltage changes in the core wire. Through shielding layers and cable structure design, external interference is reduced to ensure that the signal accurately reaches the receiving end equipment. After the signal is transmitted to the receiving device, the device parses and processes the signal, executes corresponding operation instructions, and thus achieves collaborative work between devices.
