Inputs and Outputs are used for the monitoring and controlling of a connected device or receiving signals from that device in order to trigger certain events.

This section provides a list Input/Output electric characteristics inherent in RUT955 routers.

• Digital input (DIN1): Logic low 0 - 1.2 V; Logic high 1.8 - 3 V

• Digital galvanically isolated input (DIN2): 0 - 30 V

• Analog input (voltage mode): 0 – 24 V*

• Analog input (current mode): up to 20 mA (commonly used with 4-20 mA standard sensors)

• Digital open collector (OC) output: 30 V, 250 mA

• SPST relay output: 24 V, 4 A

• Digital non-isolated input (in power socket): Logic low 0 - 5 V; Logic high 8 - 40 V

• Digital open collector (in power socket) output: 30 V, 300 mA

Note:

If you decide not to use the standard 9 VDC wall adapter and want to power the device from a higher voltage (15-30 VDC), please make sure that you choose a power supply of high quality. Some power supplies can produce voltage peaks significantly higher than the declared output voltage, especially during connection and disconnection.

While the device is designed to accept input voltage of up to 30 VDC peaks, high voltage power supplies can harm the device.

Hardware Application Examples

• Connecting relay to open collector output

• Inverting relay output polarity

• Using Inputs for security applications

• Current measurement with analog input
