SKU: VE-191 Category: Relay

A 5V 30A Single-Channel Relay Module is a heavy-duty electronic switching board designed to let low-power microcontrollers (like Arduino, ESP32, or Raspberry Pi) safely control ultra-high-current appliances. Utilizing a massive, specialized SLA/T90-style power relay, it provides full galvanic isolation to bridge digital logic with massive electrical loads. It is widely used across India to automate heavy household and industrial appliances like geysers, air conditioners, water pumps, large heating elements, and high-power industrial motors.

✨ Key Features

High-Current SLA/T90 Form Factor: Features a massive mechanical block specifically built to handle up to 30 Amperes of continuous current without arcing or overheating.
Built-in Optocoupler Isolation: Equipped with a premium PC817 optocoupler chip that isolates the control signal using light, protecting your microcontroller from heavy inductive feedback spikes.
Configurable High/Low Logic Trigger: Features an onboard plastic jumper allowing users to freely switch the input trigger between High-Level (5V) and Low-Level (0V) logic tracking.
