SKU: AT0038|MOD005 Category:


It is a 4-channel isolated 5V 10A Relay 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 a large current.

Relay output maximum contact is AC250V 10A and DC5V 10A. One can connect a microcontroller with a standard interface directly to it.

Red working status indicator lights are conducive to safe use. It has a wide range of applications such as all MCU control, industrial sector, PLC control, and smart home control.

Each relay can individually switch on/off by an opto-isolated digital input, which 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.

Specifications and Features:-

  • One normally closed contact and one normally open contact
