Solenoids
Magnet whose magnetic energy is produced by the flow of electric current
What is an Electromagnet?
Starts or stops the flow of current by closing or opening the contacts of the control device.
What are signals?
device that is pushed pulled or rotated by the individual operating the circuit.
What is the operator?
The conducting part part of the relay that acts as a switch to make or break the circuit.
What is a Contact?
The amount of electrons flowing through an electrical circuit.
What is current?
Unwanted current induced in the metal structure of a device due to the rate of change in the induced magnetic field
What is Eddy current?
is created when a N.O. P.B. and a N.O. switch are connected in parallel
What is OR logic?
Part of the push-button that is activated when the operator is pressed.
What is a Contact block?
A device that controls one electrical circuit by opening and closing contacts in another circuit.
What is a Relay?
Current that flows only in one direction.
What is direct current(DC)?
A single turn of conducting material mounted on the face of a magnetic laminate assembly or armature
What is a shading coil?
Determines the work to be done and in what order the work is to occur
What are Decisions?
An operator that selects one to eight different circuit conditions.
What is a joy-stick?
Is rated in contact life and mechanical life.
What is EMR life expectancy?
Is a substance that produces a magnetic field and attracts iron.
what is a magnet?
An electric output device that converts electrical energy into a linear mechanical force
What is a Solenoid?
Is created when 2 N.O. Push buttons are connected in series to control a load
What is AND logic?
The part of a limit switch that transfers the mechanical force of the moving part to the electrical contacts .
What is the actuator?
The number of completely isolated circuits that a relay can switch.
What are Poles?
The opposition to the flow of electrons.
What is Resistance?
Provided by manufacturers to indicate the voltages available for a given solenoid
What are voltage ratings?
The frequent starting and stopping of a motor for short periods of time.
What is Jogging?
cylindrical devices with several deep folds that expand or contract when pressure is applied.
What are bellows?
Is a switching device that has no contacts and switches entirely by electronic means.
What is a solid-state relay?
A circuit that suppresses noise and high voltage on the power lines.
What is a snubber circuit?
