Features flash-on, flash-off function, it is possible to turn on the relay for a while and then close it automatically via the command\u003c\/li\u003e\n\u003cli\u003eOnboard voltage regulator chip, supports 7~36V wide voltage power supply. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal\u003c\/li\u003e\n\u003cli\u003eOnboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption. Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current\/over-voltage proof, lightningproof \u0026amp; anti-electrostatic\u003c\/li\u003e\n\u003cli\u003eOnboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit. Onboard dedicated relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable\u003c\/li\u003e\n\u003cli\u003eReverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection. High quality relay, contact rating: ≤10A 250VAC\/30VDC.
