HUAREW 1-channle 5V relay module with optocoupler isolation supports high and low level triggering (pack of 10)

• Convenience: The relay board is designed with 1 interface, humanized design, input and output terminals, and convenient wiring.
• With indicator light: with power supply and working dual indicator lights. Power indicator (green), relay status indicator (red)
• Insulation design: The relay board is insulated with a patch optocoupler, and the insulation circuit prevents the relay switching current from damaging the E/A port.
• High quality: The module adopts normally open interface, high quality relay, the maximum load of the relay module: AC 250V/10A, DC 30V/10A.
• Wide range of applications: suitable for all kinds of single-chip microcomputers, and can be widely used in various power control occasions.
