I/O relay modules are devices used in automation and control systems to interface between digital or analog input/output signals and external loads such as motors, valves, and lights. These modules typically consist of a series of relays integrated with input/output circuitry, allowing them to receive signals from a control system and actuate the corresponding relays to control external devices. I/O relay modules are commonly used in industrial automation, building management systems, and process control applications.
