DPDT stands for double pole double throw, basically its a relay that when energized, by what ever is controlling it, it will have 2 sets of non-connected contacts "make connection" at the same time. You would use one where you have 2 separate systems that you want controlled by the same action. That help?

What is pick up of a relay?
The "pick up" of a relay is a setting at which the relay will begin to operate. Such as an overcurrent relay - if the pickup is set to 5A, when 5A is flowing through the relay, the relay will operate.
What is the difference between a relay and an auxiliary relay from constructionapplication poin of view?
I think aux relay is part of relay
Earth fault relay and an overcurrent relay Methods to energise an earth fault relay?

What the Generator lockout relay?
generator lockout relay is a relay that the output of other relays energize this relay and its out put use for tripping of generator. this relay must be reset manually
What is translay RELAY?
translay relay
2 form c relay?
A 2 Form C relay is a DPDT relay that does Break-before-make
What types of magnet either permanent or electromagnetic for AC or DC relay?
What types of magnet either permanent or electromagnetic for AC and DC relay?"how DPDT relay works?
Wiring diagram electromagnetic relay?
Relays come in many different packages. There are SPST relays, SPDT, DPDT. Check the link below to see all the relay wiring diagrams.
Can i use a DPDT relay in replase of a SPDT relay. can i use it but wire it up in a way that it would work the same way as a SPDT or can i not?
yes, just ignore the second pole that you don't need.
What does the abbreviation DPDT stands for what type of switch?
A DPDT switch is a Double Pole Double Throw switch
What does DPDT identify?
DPDT stands for Double pole, double throw. This is the equivalent to two SPDT switches controlled by a single mechanism.
How do pictures turn motors both ways?
a PIC can turn a motor both ways buy commanding a relay (DPDT), the pic can chage which way around the moter is turning by the flow of the electricicty.
Installing An Emergency Generator With A DPDT Switch?
Some emergency generators can be installed in a home using a double-pole, double-throw (DPDT) transfer switch. A DPDT switch basically prevents the emergency generator from pushing power into the utility grid where it can cause a fire or can injure a utility worker. A home that does not have a DPDT transfer switch will need to use another type of emergency generator that runs independently of the electrical wiring in the home.
How do you connect a DPDT switch so that when the switch is off an LED is on?
By connecting the LED on the other terminals in parallel
Can you wire two furnaces to one thermostat?
Yes, using DPDT relays between the thermostat and the two furnaces.
What would a 1 Form C relay and a 1 Form A and 1 Form B relay be?
Hi All answered in http://zone.ni.com/devzone/cda/tut/p/id/4782 = Relay Forms = 121 ratings | 4.61 out of 5 | Print DocumentRelays are classified by their number of poles and number of throws. The pole of a relay is the terminal common to every path. Each position that the pole can connect to is called a throw. A relay can be made of n poles and m throws. For example, a single-pole single-throw relay (SPST) has one pole and one throw, as illustrated in the following figure. A single-pole double-throw (SPDT) relay has one pole and two throws, as illustrated in the following figure: A double-pole double-throw (DPDT) relay has two poles, each with two simultaneously controlled throws, as illustrated in the following figure: Relays are then classified into forms. Relay forms are categorized by the number of poles and throws as well as the default position of the relay. Three common relay forms are: A, B, and C. Form A Form A relays are SPST with a default state of normally open. Form B Form B relays are SPST with a default state of normally closed. Form C Form C relays are SPDT and break the connection with one throw before making contact with the other (break-before-make).
What is auxiliary relay?
An auxiliary relay is a back-up relay in case the primary relay fails.
