Relay Module, Low Power 5mA Trigger Multi-Voltage 5V 12V 24V Optocoupler Isolation Module 1 Channel AC DC for Home Automation Industrial Control DIY Electronics Automotive Projects

About this item

【Patch Photocoupler Isolation】-- Our company's new product of relay module adopts patch photocoupler isolation,which has the capacity of strong driving ability, stable performance. 5mA trigger current makes it more stable to work | 【Humanized Interface Design】-- Our company's new design of relay module has optimized the interface according to the humanized needs: each interface can be connected directly through the terminal lead, which is very convenient to use. And the two different color of light can help to clearly distinguish power indicator light(green) and 4-way relay state indicator light(red) | 【Jumper Setting】-- Within this type of relay module, the high level or low level can trigger the module of each path | 【Optional Operating Voltage】-- This relay module has 3 type of module operating voltage to choose: 5V, 12V and 24V .All of this different type of voltage has the unique advantage | 【Fault-tolerant Design】-- This relay module adopts the unique design of fault-tolerant, which has the advantage of not move even if the the control line breaks and can avoid some working malfunctions
