1 channel 5v/dc self-locking relay module 250VAC 10A

The OKY3011-4 is a versatile 1-channel self-locking relay module, providing enhanced isolation and protection for remotely controlling electrical circuits. This module allows a low-voltage signal to efficiently manage a high-voltage or high-current circuit.

Overview

The OKY3011-4 relay module incorporates a bistable relay, ensuring it maintains its on or off state even after the control signal is removed. This self-locking functionality is easily activated using a single button or trigger signal to toggle the relay's state. It is ideally suited for use with microcontrollers such as Arduino, AVR, PIC, DSP, ARM, MSP430, and TTL logic.

Key Features
