4 Channel Isolated 5V 10A Relay Module opto coupler For Arduino PIC AVR DSP ARM

This 4-channel isolated 5-volt, 10-amp relay module is an optocoupler that may be controlled by a variety of microcontrollers, including Arduino, AVR, PIC, ARM, and more. It can also manage a wide range of appliances and other high-current devices.

The maximum contacts for a relay are AC 250 V 10 A and DC 30 V 10 A. It can be immediately connected to a microcontroller with a standard interface. It is safer to utilise red operating status indicator lights. Its applications are numerous and include PLC control, smart home control, industrial sector, and control of all MCUs.

Are you prepared to turn on your Raspberry Pi? There are four 5V relays with a 10A/250V rating each in this stylish relay module. With the aid of a microcontroller, it is intended to switch up to four high current (10A) or high voltage (250V) loads!

With an opto-isolated digital input that can be connected straight to a microcontroller output pin, each relay may be separately turned on or off. It can take input voltages up to 5V, however it only needs about 1.0V to turn the inputs on. It is hence perfect for 1.0V to 5V electronics.

• 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

Characteristics:

• A single, typically closed contact and one, typically open contact
• Relay coil increase and triode drive
• Pin of a high impedance controller
• Pull-down circuit to prevent malfunctioning
• Lamps for the control and power supply indicators
• Instructions for the power supply and relay are illuminated, and the disconnect is off;
• The common terminal, input signal, and begin conducting;
• Beneficial for controlling appliances;
• You can manage the 220V AC load with either a DC or AC signal;
• One ordinarily closed contact and one normally open contact exist;
• The module complies with global safety regulations, load area isolation trenches, and control.
