Description:

5V 12V 24V 30A One Channel Relay Module Optocoupler Isolation High and Low Trigger With optocoupler isolation, strong drive capability, stable performance; trigger current 5mA. Friendly interface design, all interfaces can be directly connected through the terminal leads, very convenient.

Specifications:

• Model Type: Relay Module
• No. of Channels: 1

Features:

• High-impedance controller pin
• Pull-down circuit for the avoidance of malfunction
• One normally closed contact and one normally open contact
• Triode drive, increasing relay coil
• Power supply indicator lamp
• Control indicator lamp
• With 4 fixed screw holes, a hole diameter of 3.1mm, convenient installation, and fixation

Pin Descriptions:

• DC +: DC power supply positive;
• DC -: DC power supply module negative;
• IN: Signal input terminal(support High/Low Level switch freely);
• Normally open (NO): Relay normally open;
• Common terminal (COM): Relay common;
• Normally closed terminal (NC): relay normally closed terminal

Note:

On the high-level and low-level-triggered mode, friends who do not understand, have a look:

• High-level trigger refers to the signal voltage between input and trigger and can be understood as a signal input with VCC cathode short-circuit triggered away.
• Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, which can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way 1-channel relay module connection.
