[2 Pack] DC 12V Relay Module 2 Channel Switch with Optocoupler Isolation High/Low Level Trigger

【Control Devices】The 2-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, Pi, MSP430, TTL logic etc).
