Introduction

The Relay Module is used to control larger current consuming component, like a 220V lamp. We don't recommend you use it under the inductive loads. Please attention when you use it under high voltage loads. This maybe very danger under that conditions.

Usage

The Relay Module is a normally open kind. This means the connector normally is open, when you input a HIGH voltage into the "SIG" pin, then the connector will be closed.
