Nube-iO - Connecting Wired Outputs

General: Connecting Wired Outputs


Wired outputs consist of wired output signals to be sent to other devices.  They from the Digital Output (DO), Universal Output (UO), and Relay Output (R1, R2,etc.) terminals of controllers that support wired output points.


Wired Outputs are grouped in to two main categories:

1. Digital – Only 2 possible states: ON or OFF.  Digital Outputs can produce Voltage, or activate a Switch/Dry Contact.

2. Analog – Many possible states based on a range of Voltage, or Current (specific to the output type).


Digital Outputs

Digital Outputs are connected between the Ground (GND) terminal and the selected DO or UO terminal.   

There are 2 types of Digital Outputs:
  1. Voltage - Output is either 0v or a defined voltage level (eg. 12v DC).   The Voltage Signal will be produced at the DO/UO terminal.
  2. Switched / Dry Contact / Relay - Output is either Open Circuit (OFF) or Closed Circuit (ON).  There is no polarity for this type of Digital Output.

Analog Outputs

Analog Outputs are connected between Ground (GND) terminal and the selected AO or UO terminal.  Analog Outputs are polarity sensative, with Ground (GND) being 0v (-) and AO or UO terminal being positive Voltage or Current (+).

There are two main types of Analog Outputs:

2. 0-10vdc - Output is a DC voltage signal of the range of 0v to 10v.  Voltage is produced on the AO or UO terminal.

3. 4-20mA – Output is a Current signal in the range of 4mA to 20mA.   Because this type of output signal maintains the loop Current, the Voltage on the AO/UO may vary.

Note: On many devices there are output pin configuration settings (hardware and/or software) that must be configured correctly for each different type of output.  See hardware specific instructions for these output pin configurations.
