What are the control circuits?
A control circuit is a special type of circuit used to control the operation of a completely separate power circuit. Consider a 1,000 horsepower, large industrial motor driving a water pump. The motor is connected to a high voltage electrical supply of 2,400 volts.
What are the types of control circuits?
The two types of ladder control circuits commonly used are the 2-wire control circuit and the 3-wire control circuit. The 2-wire control circuit uses maintained contact devices to control the magnetic motor starter. The 3-wire control circuit uses momentary contact devices to control the magnetic motor starter.
What are industrial control components?
Key Components of Your Industrial Control Panel Identified and Explained
- Power Circuit. This refers to any circuit that uses electricity in order to operate a load on the industrial control panel.
- Control Circuit.
- Switches.
- Terminal Blocks.
- Contactors.
- Motor Drives.
- Transformers.
- Overcurrent Protection Devices.
What does an industrial control panel do?
Industrial electrical control panels are designed and utilized for the control of mechanical machinery and equipment. Industrial control panel units are designed to handle a particular equipment arrangement and include certain devices that enable the industrial operator to control the equipment.
What are the three types of circuit control devices?
There are three type of common circuit control devices; switches, relays and solenoids. Switches, in simple terms is a two piece metal called contacts that touch to make a circuit and separate to break the circuit.
What is PLC control panel?
PLC Panel (Programmable Logic Controller Panel): Programmable Logic Controllers (PLCs) are small industrial computers with modular components designed to automate customized control processes. Integrated PLC Panel can monitor any process and provide data wherever and however you need it.
What goes in a control panel?
These components include:
- Main circuit breaker. This is like the disconnect of the main electrical panel leading into a home or office.
- Surge arresters.
- Transformers.
- Terminal blocks.
- Programmable Logic Controller (PLC).
- Relays and contactors.
- Network switches.
- Human Machine Interface (HMI).
What are the three reasons circuit control is needed?
Broadly, these serve three basic purposes:
- Remove power from a malfunctioning device.
- Apply power to a device when work is completed on it.
- Select the function or circuit desired within a device.
Why control circuits are needed?
Circuit control devices allow you to turn the device on when it is needed and off when it is not needed. Some devices, like multimeters or televisions, require the selection of a specific function or circuit. A circuit control device makes possible the selection of the particular circuit you wish to use.
