The module uses genuine quality 5V relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A. Low Voltage input (2.8V - 6V) allows you to operate on 3.3v and 5v systems. Low Trigger Voltage (1.2V - 6V) Using SMD optocoupler isolation, strong driving capability, stable performance; trigger current 5mA. Fault-tolerant design, even if the control line is broken, the relay will not move. All interfaces are available through a direct connection terminal leads. The Module can be set by jumper high or low trigger.
