YOURBOT 4-Channel Relay Control Board Module With Optocoupler, 4 Way Relay Module for Arduino.

It is 5V 10A 4-Channel Opto Coupler Relay Board Module, A variety of microcontrollers such as Arduino, AVR, PIC, ARM and so forth can Keep watch over it.

It is also able to Keep watch over more than a few 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 secure use. It has A variety of applications such as all MCU Keep watch over, industrial sector, PLC Keep watch over, smart home Keep watch over.

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 care for input voltages up to 5V. This makes it ideal for 1.0V to 5V devices.

Features:

One most often closed contact and one most often open contact

Triode drive, increasing relay coil

High impedance controller pin

Pull-down circuit for avoidance of malfunction

Power supply indicator and Keep watch over indicator?lamp
