At its core, a relay functions as an electrical switch. It acts as a mediator between the low-voltage control circuit and the high-voltage load circuit, enabling the control of a much larger electrical power with minimal input. This capability is crucial in various industrial applications where the control of heavy machinery or high-power equipment is required. Relays are adept at opening and closing circuits, providing the necessary isolation and protection for delicate control systems.
On the other hand, signal conditioning is a process that fine-tunes electrical signals to ensure optimal performance and accuracy. In industrial automation, signals are susceptible to various distortions and interferences during transmission. As such, signal conditioning addresses these challenges through the amplification, filtering, or modulating of signals to enhance their quality, making them more resilient and reliable.
