Relay board module is used for controlling higher current loads from your microcontroller development board, PC parallel port or Arduino Uno. This board has four onboard relay which can switch. Relays terminals (COM, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. This 4-Channel Relay interface board which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, 8051 and so on.
Input Voltage: 5V DC
Relay Output: 10 Amps / 250V AC
