10pcs 5V 1-Channel Relay Module Board Low Level Trigger DC AC 220V

Features:

• Isolated grooves in both the control area and load area for enhanced safety and performance.
• Power and relay action indicators visibly display connection status: on when connected, off when disconnected.
• Activates breakover between the public side and common side upon signal input.
• Serves dual functions as a microcontroller development board module and home appliance control.
• Capable of controlling both DC and AC signals, including a 220V AC load.
• Includes a permanent open and close vents contact.
• Easy connectivity via blue KF301 terminal access control cable.

Specification:

• VCC: Power interface, 5V
• GND: Ground
• IN: Control interface, requires a drive current of at least 4mA
• COM: Control circuit ground, connect to GND
• Size: approx. 41 x 16 x 16mm / 1.61 x 0.62 x 0.62 inches
• Weight: approx. 12g

Note:

• High-level flip-flops indicate trigger mode through voltage between the signal input terminal and ground; it involves a short circuit trigger between the signal input and VCC positive pole.
• Low-level flip-flops indicate an OV trigger mode voltage between the signal input terminal and ground; this is a short circuit trigger between signal input and GND negative pole.
• Please allow a variance of 1-3mm due to manual measurement.
• Due to different displays and lighting, the actual item's color may not exactly match the images. Thank you for your understanding.

Package Included:

• 10 x 1 Channel Relay Module
