Product Overview

This versatile relay module is designed for both microcontroller development and home appliance control, making it an essential tool for electronics enthusiasts and professionals alike.

Key Features

• Safety Compliance: Adheres to international safety standards with isolation slots separating the control area from the load area.
• Relay Indication: Equipped with relays that provide power and action indicators; bright when powered, dim when not.
• Signal Activation: Activates when a signal is present at the input, allowing connection between common and normally open terminals.
• Control Capabilities: Suitable for controlling both DC and AC signals, including 220V AC loads.
• Contact Options: Features both normally open (NO) and normally closed (NC) contacts for flexible applications.
• User-Friendly Connections: Blue KF301 terminals facilitate easy connection of control lines.
• Compact Design: Weighs approximately 12.4 grams with dimensions of about 4.3 x 2.7 cm.

Trigger Modes Explained

1. High-Level Triggering:

– This mode activates when there is voltage between the signal input and ground, effectively short-circuiting the signal input to VCC’s positive pole.

1. Low-Level Triggering:

– In this mode, activation occurs when the voltage between the signal input and ground is zero volts (OV), achieved by short-circuiting to GND’s negative pole.
