ECIL Junior Technician Interview Questions and Answers

PLC inputs and outputs are used to communicate with sensors, actuators, and other devices in an industrial control system.

• PLC inputs are used to receive signals from sensors or other devices.

• PLC outputs are used to send signals to actuators or other devices.

• Inputs and outputs are typically connected to the PLC using terminal blocks or connectors.

• Examples of inputs include push buttons, limit switches, and temperature s...read more

Electronic circuits are pathways through which electrical current flows, consisting of components like resistors, capacitors, and transistors.

• Electronic circuits are made up of components like resistors, capacitors, inductors, diodes, and transistors.

• They can be classified into analog circuits and digital circuits based on the type of signals they process.

• Analog circuits deal with continuous signals while digital circu...read more

A motor converts electrical energy into mechanical energy, while a generator converts mechanical energy into electrical energy.

• Motor uses electricity to produce motion, while generator uses motion to produce electricity

• Motors are commonly found in appliances, vehicles, and industrial machinery

• Generators are used in power plants, wind turbines, and backup power systems

Mechanical rectification is the process of converting alternating current (AC) to direct current (DC) using mechanical devices.

• Mechanical rectifiers typically use rotating commutators or rectifying diodes to convert AC to DC.

• Examples of mechanical rectifiers include rotary converters and motor-generator sets.

• Mechanical rectification is less common today due to the widespread use of solid-state rectifiers.

• The process of...read more

Rotating devices have moving parts while static devices do not.

• Rotating devices have components that move in a circular motion, such as motors or turbines.

• Static devices have stationary components, like resistors or capacitors.

• Rotating devices typically require maintenance for lubrication and alignment.

• Static devices are generally more reliable and have longer lifespans.

• Examples of rotating devices include electric mot...read more
