The purpose is to buffer the input for monitoring purposes
An operational amplifier is typically used where it is desirable to control a voltage over a wide range of levels; i.e., in analog mode as opposed to the on-off limits of a digital signal. An operational amplifier in simplest form will have a non-inverting and an inverting input terminal and an output terminal, each of which are analog in function. The output terminal will tie into external circuit components that eventually connect back to the inverting terminal. The key to its performance is that when a change is made to the voltage on the non-inverting input terminal, the output of the amplifier will change in voltage level, whether increasing or decreasing, to the level that causes the voltage appearing at the inverting terminal to equal that of the non-inverting terminal. In that way the output voltage is a predictible value that is useful for automatically controlling a flow valve or other device. Of course, it can also be used to just to act as a signal conditioner for sensors, audio devices and countless other applications.

Power limitation transformer circuit structure of power supply, including: an electromagnetic interference filter unit, a rectifying unit, a power factor correction section, a transformer having a primary input terminal and secondary input terminal, a pulse controlling unit connected with the secondary input terminal of the transformer, a primary power limitation circuit and at least one secondary power limitation circuit, an output current controlling unit and an output voltage controlling unit. The input terminal of the output current controlling unit is connected with the secondary output terminal of the transformer. The primary output terminal and secondary output terminal of the output current controlling unit are respectively serially connected with the primary and secondary power limitation circuits. The input terminal of the output voltage controlling unit is connected with the secondary output terminal of the transformer. The output terminal of the output voltage controlling unit is connected with the secondary power limitation circuit for controlling the magnitude of the voltage and current of the primary and secondary power limitation circuits so as to control the output power.

Because they can be used to obtain or get an output (on a series connected resistance with them) for a specific frequency of the input signal. This is the ideal case, but in fact, the resonance circuit passes a band (not a single frequency) of input signals' frequencies to take them at the output terminal. They are also termed as ( filters or filtering circuits ). They are called selective as they function as if they select signals of specific frequencies to be passed to the output.

Analog transducers convert the input quantity into an analog output which is a continuous function of time. E.g.-L.V.D.T,Thermocouple, Strain guageDigital transducers convert the input quantity into an electrical output which is in the form of pulses.
They're used for a number of purposes... testing amperage output, testing voltage output, testing circuit resistance to identify shorts or breaks in the circuit... the digital multimeters are preferred, especially in testing electronics for resistance, and they're less liable to burn out a circuit than an analog multimeter would be.

Analog Multiplexer - Two analog signals as the input, one analog signal as the output, output is the product of the two inputs.

In a BMS system, starting and stopping of a piece of equipment is through analog input analog output points.
I would use my multimeter to read the output.
Yes and no. It's...hard to explain. The monitor on the terminal is the Output device and the keyboard on the terminal is the input device.
