Product Features

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 ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic; Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
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
