4 Channel 5V 10A Relay Module with optocoupler

It’s a 4 Channel 5V 10A Relay Module with optocoupler. This relay module can relay a separate power supply relay power input of JD VCC. It has Input IN1, IN2, IN3, IN4 signal line active low, 5V 4-Channel relay board controlled directly by micro-controller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) need 50-60mA driver current

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

Features:

1. One normally closed contact and one normally open contact
2. Triode drive, increasing relay coil
3. High impedance controller pin
4. Pull-down circuit for the avoidance of malfunction
5. Power supply indicator and Control indicator lamp
6. Power supply and relay instructions, lit, the disconnect is off;
7. The input signal, signal, common Terminal and start conducting;
8. Useful for appliance control;
9. DC or AC signal, control, you can control the 220V AC load;
10. There is a normally open and one normally closed contact;
11. The module is compliant with international safety standards, control and load areas isolation trenches.
