An Isolated Relay Module is a crucial component in industrial automation and control systems, designed to provide electrical isolation between control signals and output devices. It helps protect sensitive circuits by isolating high-voltage loads from low-voltage control systems, ensuring safe and reliable operation. These modules are commonly used to control motors, lights, alarms, and other equipment through PLCs or microcontrollers. By preventing electrical noise and faults from affecting the control system, isolated relay modules enhance system stability, safety, and longevity.
