UE11-4DX3D31 Relays

The UE11-4DX3D31 is an electromechanical power relay, often used for higher current switching applications over 2 Amps. It has a number of different common applications, with its robust and compact design primarily being used in circuits that require high current connections for heavy industrial machinery.

The relay itself has two main terminals for connection, an open terminal and a common terminal. The open terminal is where the voltage is applied and when the voltage is present, this will cause the internal coil to become energized. This energized coil will then pull a set of contact points typically formed into a ‘bridge’ configuration, to create a connection between the open and common terminals, allowing power to flow.

The mechanical side of the relay relies on the use of an armature. This armature moves when the coil is energized, allowing the initial contact points to bridge together and make the required connection. The armature will generally have its own set of contact points, which allows it to form a separate connection when the voltage is removed. This helps to reset the relay for the next time it needs to be used, as well as to prevent any residual currents that could potentially damage the device.

Another common way in which this type of power relay is used is in motor control circuits. When the relay is connected to the motor’s power source, it will be used to control the direction in which the motor turns and how much speed it is allowed to rotate at. The relay operates by allowing a certain amount of current to pass through it, which then gets attracted to a ‘soft’ region that is placed on the armature. This in turn helps to prevent the motor from exceeding any predetermined speed limits.

Aside from its use in motor control circuits, the UE11-4DX3D31 is used in a range of other applications, such as gate openers and HVAC systems, where it is used to control the amount of power being sent to various components. Its flexible design also allows it to be used in applications such as circuit protection, where it can be used to interrupt power in the event of an overload or transient condition.

Overall, the UE11-4DX3D31 is a high current electromechanical power relay that is used in a wide range of industrial applications. Its simple design and rugged construction are well suited to handle heavy loads, and its ability to control the amount of power being passed, makes it an invaluable tool for any industrial circuit.
