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

Description

Control DevicesThe 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 RangeNO(Normally open) maximum load < AC 250V/10A, < DC 30V/10A. Trigger current of opto-isolator: 5mA.

Fault-tolerant DesignThe relay will not operate even if the control line is disconnected.

Universal InterfaceEquipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation.

High CompatibilityThe relay module can be controlled directly by 12V logic signals from microcontroller(8051, AVR, PIC, DSP, ARM, Pi, MSP430, TTL logic etc).
