Auxiliary Contacts
What are Auxiliary Contacts?
Auxiliary interfaces, also referred to as contractors, are electromechanical components employed in combination with basic switching components, including contactors, circuit breakers, switches, and relays. These additional switching components are directly connected to the major switching component and function at the same time. These supplementary attachments exist in a wide range of interface specifications and mounting structures to be compatible with many diverse industrial automated and control system applications.
Enrgtech, as well as other top-tier manufacturers like Schneider Electric, Siemens, ABB, Lovato, Eaton, and Schneider Electric, offer a wide selection of premium auxiliary contact blocks.
How do Auxiliary Connections Function?
Attached to the main contacts, auxiliary interfaces switch states when the main contacts do. They transfer the circuit's data to a logic controller, which instructs the connected devices whether to turn on or off. They can also be utilized as stand-alone hardware control units. Finding the appropriate auxiliary contact for the application is simple because they come in a variety of mounting options, such as a front mount or DIN rail mount, and a selection of terminal types, such as screw terminals, screw clamp terminals, and cage clamp terminals.
What are the common types of Contact Blocks?
There are different kinds of contacts designed to be used in harsh industrial conditions; the CAL19-11 Auxiliary contact block is utilized to operate auxiliary and control circuits. The auxiliary contact blocks have screw-type connection terminals that are delivered open, protected from unintentional direct contact, and marked with the appropriate function. Those that are open and those that are closed in an inactive condition. They will be labeled as normally closed (N/C) and normally open (N/O). Interlocks are created using NC contacts. Other components, such as status indicator LEDs, are switched on via NO connections.
What are the Auxiliary Contacts used for?
Auxiliary interfaces, the most common usage in the industry, are in push-button controllers since they are embedded in the start button. They are the most commonly used devices in:
- Relay logic circuits
- Solid-state electronics
- Electronics
- Industrial control systems
- Electric motors
- Other motor control applications.
