DESCRIPTION 2 Channel 5V Relay Module (Discontinued) 5V 2-Channel Relay interface board; each relay requires 15-20mA Driver Current. Equipped with high-current relay: AC250V 10A; DC30V 10A. Standard interface that can be controlled directly by microcontrollers (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic). Indication LEDs for relay output status. Activates on low level. 4 Channel 5V Relay Module 5V 4-Channel Relay interface board; each relay requires 15-20mA Driver Current. Equipped with high-current relay: AC250V 10A; DC30V 10A. Standard interface that can be controlled directly by microcontrollers (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic, active low). Opto-isolated inputs. Indication LEDs for relay output status. 8 Channel 5V Relay Module A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate the switch and provide electrical isolation between two circuits. This 8-c
