  • Configurable device address (1~255), multi devices can be cascaded on RS485 bus. Features flash-on, flash-off function, by passing argument to the command, it is possible 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
