RS485 communication: there are 2 ways RS485 communication can communicate with external device. And the device can concatenate 16 8-way extending devices through RS485 bus.
Switching value acquisition: 8-way switching value acquisition with AC 220V.
Timing: when the 8-way extending device connect with our lighting control terminal, our lighting terminal can give the right time to it directly, or system master station give the right time to it via lighting terminal.
Manual/automatic control: manual control – the device can accept the control command from connected lighting control terminal or system master station to output switching signal. Automatic control – the device can output switching signal automatically at regular time according to the control strategy from lighting control terminal or system master station.
Apply to street lamp lighting management solution, tunnel lighting management solution, nightscape lighting management solution, outdoor lighting integrated management solution, etc.
