Control Panel

Electrical control panels have designed and used to control mechanical equipment. Each has designed for a specific equipment configuration and includes devices that allow the operator to control specific equipment.

The control panel consists of a controller. The controller that can PLC, DCS, relay or any other type. It provides a digital signal input signal to the MCC board to start the motor. The control panel operates on the PLC / DCS program or relay logic. Devices usually connect to the control panel. The control panel also has indicators for interoperability. Currently single panel uses separate control and MCC panel.

PLC automated control panels are superior to traditional relay based systems due to the ease of modification, size reduction, remote communication media and technological advancement. The control system engineers provided PLC-based panels from Alan Bradley, Siemens, Modicon, GE Fanuk PLC. Control systems from small I / O application to complex I / O systems are provided by engineers. Control system engineers have developed communication software for remote communication of PLC panels of various protocols. HMI / MMI are provided to deliver various messages to the operator with PLC based panels. To effectively control the system.

Electrical Control Panel Components

There are eight types of electronic components in an electronic panel box that define and organize the various functions performed by the panel. These components include:

  • Major circuit breaker. This is like disconnecting the main electrical board to a home or office. Major circuit breakers in most industrial applications behave between 120V-480V.
  • Arrestees. This component prevents lightning strikes or damage to the electrical components in the utility panel due to high voltage.
  • Transformers. Depending on the incoming voltage, the transformer may reduce the voltage to 120V for different components. Or reduce the voltage to 24V when the incoming power is 120V.
  • Peripheral blocks. These blocks help to organize and distribute the wire group from different sources to different electrical devices.
  • Programmable Logical Controller (PLC) .This is essentially a CPU included in the control panel. This unit is the brain of the control panel and provides monitoring and control of various mechanical processes. Manufacturing equipment includes various inputs and outputs for mechanical work and beyond.
  • Relays and contactors. These active / inactive switches control the mechanical functions based on the commands received from the PLC. The small relay controls activities such as lights and fans. Larger relays, known as contacts, control more advanced functions such as motors.
  • Network switches. The Control Panel Communication Center facilitates communication between network switches PLC. And various network compatible devices in the product line.
  • Human Machine Interface (HMI). These components allow the operator to monitor or control certain functions of the machinery. Common HMIs include video monitors, joysticks, buttons, switches, and keyboards.
