Sensors send incoming signals either digital or analog to PLC. There are a lot of types of sensors: inductive, capacitive, temperature, optical, etc.
In a PLC system, FUN typically stands for Function. It is used to define specific functions or operations that the PLC will execute based on the input signals received. Each function typically corresponds to a specific task, such as controlling a motor, monitoring a sensor, or activating an output device.

The function of a furnace heat sensor is to detect the temperature inside the furnace. It contributes to the overall operation of the furnace system by ensuring that the temperature remains at the desired level, allowing the furnace to function efficiently and safely.
To protect the low voltage electronic components in the PLC from High Voltages/Currents such as in voltage spikes.
A sensor, no. If that is a feature on a 1996, it is a function of the power door lock system.

The function of a furnace ignitor sensor is to detect when the furnace needs to ignite and to trigger the ignition process. It contributes to the overall operation of a heating system by ensuring that the furnace ignites properly and efficiently, allowing the system to generate heat effectively.
The sensor decide when the wheels are losing traction. When this happens, the controller engages a valve system in the vehicle that controls the brake fluids in the lines.
Sensors put out a wide variety of output...4-20Ma, 0-5 VDC, 120 VAC, etc. You cannot connect the O/P signal of the sensor to the input of the PLC - unless the voltage O/P from the sensor does not match the I/P voltage range of the PLC. In that case, some sort of relay / opto-isolator or some sort of pull-up / pull - low resistor could solve your problem.
Yes, you need coolant around the sensor probe to have it function properly.
The ignition sensor in a furnace is responsible for detecting when the pilot light or main burner flame is lit. It ensures that the fuel is ignited properly, allowing the heating system to function efficiently and safely. If the ignition sensor fails, the furnace may not start or stay lit, leading to a lack of heat in the home.
PLC or programmable logic controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly line, amusement rides, or lighting fixtures.
