5pcs 5V 1-Channel Low-Level Trigger Relay Module, AC/DC 220V Interface Board for MCU

Features

• Isolation groove separating the control area and load area.
• Power and relay action indicators light up when connected and turn off when disconnected.
• Signal input triggers connectivity between public and common sides.
• Suitable for microcontroller development board module and home appliance control.
• Capable of controlling DC or AC signals, including 220V AC loads.
• Equipped with permanent open and close vent contacts.
• Easy connection via blue KF301 terminal access control cable.

Specification

• VCC: Power interface, 5V
• GND: Ground connection
• IN: Control interface, requires at least 4mA drive current
• COM: Control circuit ground, connect to GND
• Dimensions: Approximately 41 x 16 x 16mm (1.61 x 0.62 x 0.62 inches)
• Weight: Approximately 12g

Note

1. High-level flip-flops indicate trigger mode based on voltage between signal input and ground; it's a method of short circuit triggering between signal input and positive VCC.
2. Low-level flip-flops indicate OV trigger mode voltage between signal input and ground; it's a method of short circuit triggering between signal input and negative GND.
3. Allow for 1-3mm variation due to manual measurement.
4. The actual color of the item may vary due to different displays and lighting conditions.

Package Included

• 5 x 1 Channel Relay Module
