What does nc and no mean in electrical terms?
nc: Normally Closed (contact is closed when power is not applied) no: Normally Open (contact is open when power is not applied) Applies to a relay ex...: when power is applied to a relay the no(Normally Open contact will close and allow current to flow between two terminals on relay).
Will a relay with NC contacts provide logic function that is similar to a NOT logic gate?
yes we can implement the 'NOT' gate operation by using a relay. At first we have to know the logic of NOT gate. when i/p is high it will give o/p high and vice versa so for implementing this opertion via relay we have to use the relay contact "NC".i.e normally closed then only it is possible. By considering that we are using the NC contact of the relay then when we energise the coil of the relay the NC contact will change over to NO so it is similar to logic opertion i/p high --- o/p low Ex: the microwave oven won't get energised till the door is closed .
I have a Motion detector has a 6 wires. 2 for NC 2 for 12V and 2 for Tamp. It says to put the N.C to burgular protection zone on the control panel how can i connect the NC to a 12V relay instead?
I'm assuming you want the detection of motion to trigger some other event/system.In that case, you need to use the NC wires as a 'switch' to trigger the relay's coil.Apply the power supply's +12v to one NC wire, the other NC wire to relay coil positive, and the relay coil negativeto the power supply's 0v (negative or common) wire.You will also need to provide the 12 volt power to the detector itself (it also needs power to function). Of the two leads you have marked '12v', one should be positive and the other negative. Connect these to the appropriate positive or negative wires from the power supply.This will mean that during normal (no motion detected) operation, the normally closed (NC) contacts on the detector will keep the relay coil energized until motion is detected. Then the relay coil will de-energize.This is important because: The NO and NC contacts on the relay will be in the listed states while de-energized. In your case, they will be opposite of what is listed because in a normal condition your relay will be energized. This is because the sensor has NC contacts instead of NO contacts.In short: Whatever you want to happen during motion detection should be wired to the normally closed contacts on the relay (because relays are considered de-energized in the normal state, but yours will be energized in the normal state).*** (cough, cough) NERD!!!
What does an NC mean on a report card mean?
No Credits.
It will not. This relay is a Normally Open relay construction. The contacts are closed only when power is applied to the relay coil. You must use either an SPST-NC (Single Pole Single Throw – Nor?
It will not. This relay is a Normally Open relay construction. The contacts are closed only when power is applied to the relay coil. You must use either an SPST-NC (Single Pole Single Throw – Normally Closed) construction or an SPDT (Single Pole Double Throw) type of construction so a contact closure is presented when there is no power applied to the relay coil.
How does a normally closed contact work?
De-energize it and note the position of the contacts.
What does the abbreviation nc near a connector pin mean?
nc means "not connected"
What does 400m relay mean?
You mean a 4x400m relay? Basically it means that you have four people in a relay, and each person runs 400 meters once. :)
How many swim in a relay team?
It depends what relay you mean - a normal relay has four swimmers (e.g. an IM relay or a freestyle relay) bu relays such as a cannon relay can have more
In electronics what does NC mean?
NC on a schematics typically stands for "No Connection" meaning that nothing is to be connected to that node.
What is dmt and idmt relay?
DMT relay stands for definitive mean time, and IDMT stands for inverse definitive mean time. In IDMT relay, there is a minimum time delay with magnitude.
Where is the main relay switch for a 240sx?
If you mean the ignition relay its in the drivers footwell behind the fust box. brown relay on top
