5V 10A 4-Channel Optocoupler Relay Board Module

It is 5V 10A 4-Channel Optocoupler Relay Board Module, A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it.

It is also able to control various appliances and other types of equipment with large current.

Relay output maximum contact is AC250V 10A and DC5V 10A. One can connect a microcontroller with standard interface directly to it. Red working status indicator lights are conducive to the safe use. It has a wide range of applications such as all MCU control, industrial sector, PLC control, smart home control.

Ready to get switching on your Raspberry Pi?! This neat relay module features 4 x 5V relays rated at 10A/250V each. It is designed to switch up to 4 high current (10A) or high voltage (250V) loads with the help of microcontroller!

Each relay can individually switch on/off by an opto-isolated digital input, which that can connect directly to a microcontroller output pin. It only requires a voltage of approx 1.0V to switch the inputs on but can handle input voltages up to 5V. This makes it ideal for 1.0V to 5V devices.

Features:

• One normally closed contact and one normally open contact
• Triode drive, increasing relay coil
• High impedance controller pin
• Pull-down circuit for avoidance of malfunction
• Power supply indicator and Control indicator?lamp
• Power supply and relay instructions, lit, disconnect is off;
• Input signal, signal, common Terminal and start conducting;
• Useful for appliance control;
• DC or AC signal, control, you can control the 220V AC load;
• The module is compliant with international safety standards, control and load areas isolation trenches.

Note on the high level and low level-triggered mode, i.e.

• 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 input terminal and Earth OV trigger, can be understood as signal input terminal and the GND negative electrode short circuit triggered a way 1-channel relay module connection
