Relay Module Active High/Low Switchable 5v/12v/24v Optocoupler Isolator Isolated Trigger Switch for Arduino

Description:

The module uses genuine quality relay, normally open interfaces
Using SMD optocoupler isolation, driving ability, stable performance
The module can be high or low by a jumper setting trigger
Fault-tolerant design, even if the control line is broken, the relay will not operate
The power indicator (green), the relay status indicator (red)
The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient

Specification:

Maximum load: AC 250V/10A, DC 30V/10A
Trigger current: 5mA
