- Configurable device address (1~255), multi devices can be cascaded on RS485 bus. 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
- Onboard 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
- 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. Onboard dedicated relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable
- Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection. High quality relay, contact rating: ≤10A 250VAC/30VDC. Rail-mounted ABS case, easy to install, safe to use. 3 LEDs for indicating the MCU status and signal transceiving status
