The 6-30V 1-Channel Relay Module with Adjustable Timing Cycle and LED Display is a multifunction programmable timer relay module designed for delayed switching, automatic ON/OFF cycling, pulse control, and timed equipment operation. The module combines a programmable timing controller, single relay output, push-button controls, and an LED display in one...

The 2 Channel 5V Relay Module with Optocoupler Protection is a dual-channel switching module designed to control two AC or DC electrical loads independently using low-voltage signals from a microcontroller or digital control circuit. The module operates from a 5V DC supply and typically uses two SPDT electromechanical relays, each...

The SPDT Relay 12VDC – PCB Mount 5 Pin is a compact electromechanical power relay designed to switch AC or DC electrical loads using a 12V DC coil supply. Featuring a Single Pole Double Throw (SPDT) contact arrangement, the relay provides Common (COM), Normally Open (NO), and Normally Closed (NC)...

The SPDT Relay 5VDC – PCB Mount 5 Pin is a compact electromechanical relay designed for switching high-voltage or high-current loads using a low-voltage 5V DC coil. Featuring a Single Pole Double Throw (SPDT) contact configuration, the relay provides Normally Open (NO), Normally Closed (NC), and Common (COM) terminals, making...

The 5V 1 Channel Relay Module is an electromechanical switching module designed to allow low-voltage microcontrollers and development boards to safely control high-voltage AC or DC loads. Featuring a high-quality 5V relay, transistor driver circuitry, and status indication LEDs, the module provides a simple and reliable interface for switching electrical...

A relay is an electrically operated switch. It consists of a set of input terminals for single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as making contacts, breaking contacts, or combinations thereof. Relays...
