From Basic Switching to Timed Sequences: Explore Our General Purpose Relays, Timers, Impulse Relays, and Step Relays.
Power control relays are essential components for implementing automation logic, managing electrical loads, and ensuring precise system operation. LETOP offers a selection of high-quality Power Control Relays designed for reliability and performance. This includes General Purpose Relays for basic switching, Timer Relays for time-based control, Impulse Relays for latching functions, and Step Relays for sequential operations. Our diverse range of services can help you meet your specific control needs.
Built for durability and consistent switching operations.
Manufactured according to relevant IEC standards, ensuring safety and compatibility.
Each relay type is engineered for precise execution of its specific task, including timing, latching, sequencing, and switching
Standard DIN rail mounting and clear terminal markings facilitate easy installation in control panels.
Electromechanical relays providing simple, reliable switching of circuits based on a coil signal. Ideal for isolating control circuits, interfacing different voltage levels, or switching moderate loads.
Features:
Various contact configurations (NO, NC, CO/SPDT, DPDT).
Multiple AC/DC coil voltage options.
Defined current ratings for contacts.
Often available with LED indicators and test buttons.
Common Uses:
Control panel logic, signal amplification, basic load switching (lights, fans, solenoids).
Timer relays can either activate or deactivate their contacts after a pre-set time delay following an input signal (trigger). Essential for timed sequences and process control.
Key Features:
Adjustable time ranges (milliseconds to hours).
Various timing functions: On-Delay, Off-Delay, Interval, Cyclic, etc.Multi-voltage input options.
Clear time setting interfaces (dials or digital).
Common Uses:
Motor start delay (star-delta), timed machine operations, lighting control duration, process timing.
Impulse relay also known as latching or bistable relays. They change the state of their contacts (open/close) with each input pulse and maintain that state even after the pulse is removed. The coil only gets energized briefly.
Key Features:
Energy saving (no continuous coil power needed to hold state).
Contacts remain in position during power outages.Typically controlled by momentary push buttons.
Common Uses:
Lighting control from multiple locations (replacing complex wiring), simple sequence memory, energy management applications.
Step relays designed to sequentially switch between multiple output circuits each time an input pulse is received. They cycle through a predefined sequence of contact states.
Key Features:
Defined number of steps or output contacts.
Progresses one step per input pulse.
Can be used to control multiple loads in a specific order.
Common Uses:
Multi-stage lighting control, sequential starting of pumps or fans, simple machine operating sequences.
Choosing the right relay depends on your specific need: basic switching (GPR), time delay (Timer), state holding (Impulse), or sequencing (Step). Our technical team is available to assist you in selecting the optimal relay for your application.
