2-Channel DC 5V Relay Module, Active-Low, with Optocoupler
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.
Specification:
- Number of Relays: 2
- Control signal: TTL level
- Rated load: 7A/250VAC; 10A/125VAC; 10A/28VDC;
- Contact action time: 10ms/5ms
- Current: 15-20mA per channel
