Description: Relay Module DC 12V Dual Channel Relay Control Module With Screw Terminal 

12V 2 Channel Relay Module DC 12V Relay Module 12V Relay Control Module 2 Channel For Arduino Dual Channel 12V Relay Module Switches Circuit

This 2 Road/Channel Relay Module (with light coupling) 12V module meets the safety standard as control areas and load area have the isolation groove. Optical coupling isolation module.

The triggering of the 2 Road/Channel Relay Module is reliable, more stable. The double FR – 4 circuit board design, high-end SMT process. It has power and relay operation instructions. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy.

The inputs of the 2 Channel 12V Relay Module are isolated to protect any delicate control circuitry.

Features:

• Equipped with high-current relay 10A@250VAC / 10A@30VDC
• It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc
• High-quality screw terminals (Terminal Block) provided (C, NC, NO) for quick and easy connection
• A freewheeling diode to protect your microcontroller
• Input Signal Pin connected to Burg stick for easy accessibility

Meaning of High level and Low-level:

• High-level trigger refers to using the anode voltage at the VCC connection way of a trigger and triggers the end when the trigger side has a positive voltage or to trigger voltage when the relay is off.
• Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.

Module interface:

• The positive (according to the relay voltage VCC: connect power supply)
• GND: connect power negative
• IN1: relay module (effective) high-level trigger signal trigger end
• IN2: relay module (effective) high-level trigger signal trigger end
