Contactors and starters

Contactors and Control relays are electrically operated switches used for switching of loads and for controlling the electrical circuit respectively. Contactor and Control Relay work on same principle. They are basically electrically operated solenoid switches that are designed for the switching or control the loads.

A contactor is an electrically controlled switch like a relay. Whereas a starter is a contactor with the addition of an overload relay. A contactor applies voltage to a contactor coil to close the contacts and to supply and interrupt power to the circuit.

There is different version of contactors are available, 4 NO contacts; 3 NO contacts and 1 NC contact; and 2 NO contacts and 2 NC contacts. The relays are ideally suited for use as coupling or interface contactors, especially if used to control large contactors directly from a PLC.

Relays are switches that open and close circuits electromechanically or electronically. Timers control timing in applications where functions need to be delayed or loads need to be maintained for a predetermined period.

Time delay relays control the flow of electrical power and can be used to control power to many different types of electrical loads. Combining electromechanical output relay capability with control circuitry, these relays are pre-engineered to perform up to eleven time delay functions.

Overload relays protect the motormotor branch circuit, and motor branch circuit components from excessive heat from the overload condition. Overload relays are part of the motor starter (assembly of contactor plus overload relay). They protect the motor by monitoring the current flowing in the circuit.

Overload protection relays prevent motor damage by monitoring the current in the motor circuit and breaking the circuit when an electrical overload or a phase failure is detected. Since relays are much cheaper than motors, they provide an affordable way of protecting motors.

There are wide range of Push Buttons are Signal Towers in our range is available.

PROGRAMMABLE LOGIC CONTROLLER (PLC) is an industrial Computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices. That is, you can mix and match the types of Input and Output devices to best suit your application. These are used for industrial automation to automate different electro-mechanical processes. It was introduced to eliminate issues such as high-power consumption that arose from the use of relays to control manufacturing processes.

variable frequency drive controls the speed of an AC motor by varying the frequency supplied to the motor.  The first step in this process is to convert the AC supply voltage into DC by the use of a rectifier. DC power contains voltage ripples which are smoothed using filter capacitors. The most common uses of a VFD are for control of fans, pumps and compressors, and these applications account for 75% of all drives operating globally. Soft starters and across-the-line contactors are other, less sophisticated types of motor controllers.

Soft Starter is a device that starts motors with reduced power supplied at start-up. Reducing the power reduces potentially damaging electrical and mechanical shocks on the system. As the name implies, starters "start" motors. They can also stop, reverse, accelerate and protect them.Soft starters are commonly used in industrial applications that have a high inertia load that requires a large inrush of current. One example of this is an Air Scrubber or Dust Collector. These will have large fans inside.
