Features:

• Optocoupler isolation
• Good in safety. In power system and high voltage system, the lower current can control the higher one, able to control various appliances and other equipment with high-current current.
• Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
• Indication LEDs for Relay output status.
• With a normally-open (NO) and a normally-close (NC) contact.
