5V Relay Module, 2 Channel Module Power Board with Optocoupler Isolation High and Low Level Trigger(5V)

【Stable Performance】The module adopts high-quality Relays with normal interface and maximum load: AC 250V/10A, DC 30V/10A. Using SMT optocoupler isolation, it has strong driving ability and stable performance; trigger current is 5mA; Modules can be triggered by setting high or low levels through wire jumper 【Fault-tolerant Design】This 2 Channel Relay Module with Fault-tolerant design,even If the control line breaks,the relay will not move. Power indicator light (green), 2-way relay state indicator light (red). 【Humanized Interface Design】This 2 Channel Relay Module with Humanized interface design, all interfaces can be directly connected through the terminal lead, which is very convenient. Equipped with 4 fixed screw holes, easy to install. Standard interface that can be controlled directly by microcontroller (Arduino ,, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) 【More Choice】 Relay module operating voltage is 5V,12V,24V for choice. Each path of the module can be triggered by the high level or low level through a jumper setting 【After-sales Service】As a responsible seller, we promise that 100% Money Refund/ New Replacement and within 24h online answer to your any questions.
