MAIN CONCEPTS:Definition and Function : A contactor is a device used to make and break electrical circuits, primarily for controlling high voltage motors safely. It acts as an intermediary between a PLC and high voltage equipment to prevent damage to the PLC from electrical surges.
MAIN CONCEPTS:Operation : Contactors operate with a low voltage coil (usually 24V DC) that, when energized, creates an electromagnetic field to close contacts and allow power to flow to the motor. The PLC controls this coil, thereby managing the motor indirectly. Contactor vs. Relay : While both contactors and relays use coils and contacts to control devices, contactors are designed for higher current and voltage applications compared to relays, which are suited for smaller, low voltage devices.
MAIN CONCEPTS:Wiring Details : Contactors have specific terminals for connecting power (L1, L2, L3) and device wiring (T1, T2, T3). Additionally, they feature a feedback contact to signal the PLC when the contactor is functioning correctly or if there is a fault.
Summary and Usage: Contactors are essential for safely controlling heavy electrical devices via a PLC, preventing direct connection and potential damage. The key difference from relays is their capability to handle higher power applications.
