InGateway Documentation, Release 0.0.1
4.5.1.3 DTU2
The parameters are same as those of DUT1.
4.5.2 I/O Interfaces
The relay output is ON by default. You can set the relay output status to OFF or ON, or set the OFF timer
to enable relay output to turn on automatically.States of I/O interfaces are as follows:
• Digital Input
–
When the digital input mode is wet contact, the voltage of +10 V to +30 V maps to state 1.
–
When the digital input mode is wet contact, the voltage of 0 V to +3 V maps to state 0.
–
When the digital input mode is dry contact, the state is 1 if the terminal is connected.
–
When the digital input mode is dry contact, the state is 0 if the terminal is disconnected.
• Analog Input
–
The analog input status is determined based on the current or voltage obtained from the analog
input interface.
• Relay Output
–
The default status is ON. You can change the status of a relay output interface manually. The
relay output interface stays ON if you do not change its status in the Action field.
–
Action
* OFF: turns off relay output.
* ON: turns on relay output.
* OFF -> ON: specifies the duration after which the relay input interface turns ON.
* ON -> OFF: specifies the duration after which the relay input interface turns OFF.
The I/O interface parameters are described as follows:
• Digital Input
–
Mode: Options are Shutdown, Dry Connect, and Wet Connect.
* Shutdown: disables the I/O interface.
* Dry Connect: determines the I/O interface status based on whether the input is on or off.
* Wet Connect: determines the I/O interface status based on the input voltage.
• Analog Input
–
Mode: Options are Shutdown, 0-20mA, 4-20mA, 0-5V, and 0-10V.
