Monitor - Relay OutputA monitor with relay output is a type of industrial control device that is used to monitor the status of a system or process and provide an electrical output signal in response to certain conditions or events. This output signal can be used to control other devices or systems, such as alarms, lights, or other indicators. A monitor with relay output typically includes one or more input channels that can be connected to sensors or other monitoring devices, and a built-in relay or other type of output device that can be activated based on the input signals. These monitors are commonly used in industrial automation and control applications to provide real-time monitoring and control of a variety of different processes and systems.
