Background

The solid-state relay is a new type of contactless switch device composed of solid-state electronic components, and it uses the switching characteristics of electronic components to achieve the purpose of contactless and spark-free connection and disconnection of circuit, so it is also called "contactless switch". The solid-state relay is a four-terminal active device, wherein two terminals are input control terminals, the other two terminals are output controlled terminals, and the middle part adopts photoelectric isolation as electrical isolation between input and output. When a direct current or pulse signal is applied to the input end, the output end can be changed from an off state to an on state, so that a large load can be controlled. The bistable circuit is always in the original stable state under the action of no external trigger signal. Under the action of an external input trigger signal, the bistable circuit is turned from one stable state to another stable state.

The FSU is the upper-level equipment of the monitoring module, and has the main functions of periodically collecting various information transmitted by each monitoring module, processing data, storing, setting parameters and managing alarms for the information, receiving and quickly responding to commands from the monitoring center at any time, communicating with the monitoring center, and transmitting telemetering, telesignaling and remote control data between the monitoring module and the monitoring center.
