5V 1 Channel Level Trigger Optocoupler Relay Module

The module uses a quality relay with a normally open interface
Using SMD optocoupler isolation, driving ability, stable performance
The module can be set high or low with a jumper setting trigger
Fault-tolerant design, even if the control line is broken, the relay will not operate
A power indicator (green) and a relay status indicator (red)
