Relay Module, 2 Channel Module Board with Optocoupler Low Level Trigger Expansion for Arduino 5V/12V/24V(12V)

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. Stable Performance --- The 24v relay 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 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) 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). after-sales service --- As a responsible seller, we promise that Money Refund/ New Replacement and within 24h online answer to your any questions.
