What type of control does a motor starter provide in a PLC system?

In the context of a PLC (Programmable Logic Controller) system, a motor starter primarily provides power control. Motor starters are designed to safely and efficiently control the electrical power delivered to a motor. They do this by enabling or disabling the electrical supply to the motor based on the control signals from the PLC.

When a motor starter is engaged, it allows power to flow to the motor, enabling it to start, and when the starter is disengaged, it cuts off power, stopping the motor. This fundamental ability to manage the electrical supply is essential for protecting both the motor from overloads and the entire system from electrical faults.

While other forms of control, such as speed or directional control, can be achieved through additional devices or programming within the PLC system, those are not the primary function of a motor starter. Therefore, the primary role of a motor starter is centered around effective power control, making it the correct choice in this context.
