Automation Using PLC's


1. Inverter / AC Drive, it is a device used to control a motor bike production machines.

2. Dc Drive, it consists of an SCR (Silicon Controlled Rectifier) bridge, which converts the incoming three-phase or single AC volts to DC volts. During this conversion process the DC drives can then regulate speed, torque, voltage and current conditions of the DC motor.

3. Servo Drive, it can be used in CNC machining, factory automation, and robotics, among other uses. Their main advantages of DC or AC motors are the addition of the motor feedback. This feedback can be used to detect unwanted motion, or to ensure the accuracy of the commanded motion.

4. PLC Programmable Logic Controller as programmed control system using software to control automation system.

5. Switching power supply
