4 C0hannel Relay module with Optocoupler
Description:
1. Maximum load: AC 250V/10A, DC 30V/10A
2. SMD optocoupler isolation, strong driving ability,
stable performance: trigger current 5mA.
3. The module voltage 5V
4. Each channel module can be set high or low
triggered by jumper.
5. Fault-tolerant design, even if the control line is
broken, the relay will not operate.
6. Power indicator (green), 4 relay state indicator (red)
7. Interface design user-frendly, all interfaces are
available though the wiring termenal direct
connection leads, very convenient.
