5V 1-channel relay module, shielded with optocoupler, supports high and low level triggers

The module uses genuine quality relays with normally open interfaces. Maximum load: AC 250V/10A, DC 30V/10A. It uses SMD optocoupler insulation, providing high driving capability and stable operation. Triggering current: 5mA. The module's operating voltage is 5V. The module can be set high or low using a jumper adjustment trigger. It features a fault-tolerant design; even if the control line is broken, the relay will not operate.
