This is a single-channel optocoupler isolated relay module that uses genuine high-quality relays. It has the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A.
This module is an SMD optocoupler isolation with strong driving ability and stable performance. 
Its trigger current is 5mA and the working voltage is 5V, 12V and 24V are available. 
It features two indicators LEDs:
Power indicator (Green) and relay status indicator (red).
The module has a trigger level selection terminal, each relay trigger level can be individually controlled, through the short-circuit cap to control.
When there is trigger signal input, relay disconnect and load goes off the work. 
The module can be set to high or low-level trigger by jumper:
     A. When the jumper is shorted to LOW, it is triggered at low level.
     B. When the jumper is shorted to high, the trigger is high.
