sible to turn on the relay for a while and then close it automatically
Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal Onboard 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 & anti-electrostatic Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more stable driving ability Supports passive and active digital input, with bi-directional optocoupler isolation, built in debouncing algorithm. The relay supports digital input linkage control or toggle control Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection High quality relay, contact rating: ≤10A 250VAC/30VDC Rail-mounted ABS plastic enclosure, easy to install, safe to use Multiple LEDs for indicating the MCU status and signal transceiving status Specifications
