Valefod DC 12V Relay Module 1-Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger, Pack of 10

Key features

• 【Control Devices】The 1-channel relay module uses genuine high quality DC12V relay and SMD opto-isolator supporting high/low level trigger, widely apply to control various AC/DC appliances, and other devices with large current.
• 【Load Range】NO(Normally open) maximum load < AC 250V/10A, < DC 30V/10A. Trigger current of opto-isolator: 5mA.
• 【Fault-tolerant Design】The relay will not operate even if the control line is disconnected.
• 【Universal Interface】Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation.
• 【High Compatibility】The relay module can be controlled directly by 12V logic signals from microcontroller(8051, AVR, PIC, DSP, ARM, Raspberry Pi, MSP430, TTL logic etc).
