Wiring Guidelines

In order to ensure that the device will operate properly and to avoid electromagnetic interference:

• Use a metal cabinet. Make sure the cabinet and its doors are properly earthed.

• Use wires that are properly sized for the load.

• Use shielded twisted pair cables for wiring Analog I/O signals; do not use the cable shield as a signal common (CM) / return path.

• Route each I/O signal with its own dedicated common wire. Connect common wires at their respective common (CM)
  points at the I/O module.

• Individually connect each 0V point and each common (CM) point in the system to the power supply 0V terminal, unless
  otherwise specified.

• Individually connect each functional ground point ( ) to the earth of the system (preferably to the metal cabinet chassis).
  Use the shortest and thickest wires possible: less than 1m (3.3’) in length, minimum thickness 14 AWG (2 mm2 ).

• Connect the power supply 0V to the earth of the system.

• Earthing the cables’ shield:

• Connect the cable shield to the earth of the system – preferably to the metal cabinet chassis. Note  that the shield must be connected only at one end of the cable; typically, earthing the shield at theUIA-0402N end performs better.

• Keep shield connections as short as possible.

• Ensure shield continuity when extending shielded cables.

NOTE For detailed information, refer to the document System Wiring Guidelines, located in the Technical Library in the Unitronics’ website.

Wiring the Power Supply

This module requires an external 24VDC power supply.

• The 0V of the UIA-0402N must be connected to the HMI Panel’s 0V. Ignoring this directive may damage the device.
• In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.

Connect the 24V and 0V terminals as shown in the accompanying figure.

Wiring the Analog Inputs

• NO The inputs are not isolated.

• TE Each input offers two modes: voltage or current. You can set each input independently. The mode is determined both by
  wiring and by the hardware configuration within the software application.

• Voltage and current modes use distinct points. Connect only the point associated with the selected mode; leave the other point unconnected

• Each input has its own common point (CM0 for I0, etc.).

Voltage

Wiring the Analog Outputs

• NO The outputs are not isolated.
• TE Each output offers two modes: voltage or current. You can set each output independently. The mode is determined both by wiring and by the hardware configuration within the software application.
• Voltage and current modes use distinct points. Connect only the point associated with the selected mode; leave the other point unconnected.
• Each output has its own common point (CM4 for O0, CM5 for O1). Connect each analog output using its corresponding CM point.
• Do not connect CM4 or CM5 to the system 0V.
• Do not use points CM4 or CM5 for any purpose other than connecting the analog output load. Using them for any other purpose may damage the module.

Notes:

1. The 4-20mA input option is implemented using 0-20mA input range.
2. The UIA-0402N measures values that are up to 1.5% higher than the nominal input range (i.e. Input Over-range). Similarly, it will be able to output values that are up to 1.5% higher than the  nominal output range (Output Over-range).Note that when the input overflow occurs, it is indicated in the corresponding system tag while the input value is registered as the maximum permissible value. For example, if the specified input range is 0–10V, the Over-range values can reach up to 10.15V, and any input voltage higher than that will still register as 10.15V while the Overflow system tag is turned on.
3. Step response and update time are independent of the number of channels that are used.
4. See LED Indications Table above for description of the relevant indications. Note that the diagnostics results are also indicated in the system tags and can be observed through the UniApps™ or the online state of the UniLogic™.
