  • Page 2 Indien de apparatuur wordt gebruikt op een wijze die niet is gespecificeerd door de fabrikant, dan bestaat het gevaar dat de beveiliging van de apparatuur niet goed werkt. Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 3 • Mounting: the type of protection is “Ex nA IIC T4 Gc”, comply to Standards EN 60079-0:2012+A11:2013 and EN 60079-15:2010. Certificate DEMKO 16 ATEX 1780X. 1719-PSDC • Mounting: the type of protection is “Ex nA IIC T4 Gc”, comply to Standards EN 60079-0:2009 and EN 60079-15:2010. Certificate PF 08 CERT 1234 X. Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 4 • Avoid electrostatic charges. For example, plastic parts must always be cleaned using a damp cloth, and never using a dry cloth. • Affix a warning sign that is easily recognizable to the inside of the enclosure. The sign must read as follows: “WARNING — avoid electrostatic charge”. Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 5: Adapter Components

    In the Add-on Profile display, on the Module Info page, the Internal State of the adapter shows Run mode regardless of the status of the controller (Program mode or Run mode). • Modules can only be reset by inhibiting the module through the Add-on Profile. Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 6: Installing The Backplane

    • Never supply a control voltage to X03.1…X03.3. On backplanes 1719-A8, output deactivation of the I/O modules can be controlled by a voltage-free contact only. • Only operate multiple adjacent backplanes using a common contact to avoid equalizing currents. Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...

  • Page 9: Inserting And Removing Modules

    Remove the modules by positioning your thumb and index finger on the top and bottom of the module and pulling. If necessary, adjust the information on the label carrier above the I/O modules. Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 10: Installing The Separation Plate

    Hook the catch onto the label carrier at the top of the chassis. Label carrier Bottom of chassis Top of chassis Insert the pin into the plastic holder at the bottom of the chassis. The pin snaps into place Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 11: Field Wiring

    You can code the front sockets of the I/O modules and terminals so that the terminals and the associated field devices can be assigned to exactly one front socket. Use the 1719-CP coding pins for the following terminal blocks: 1719-TB6, 1719-TB6S, 1719-TB8, 1719-TB8S, 1719-TB8Sx2, 1719-TB8x2, 1719-TB6F, 1719-TB8F, 1719-TB8x2F. Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 12: Line Fault Detection

    If you operate the 1719-IR4B I/O module in a 2-wire configuration, the wire resistance amounts to that of a resistor that is connected in series to the sensor and affects the measurement result. To avoid measurement errors, the wire resistance must be measured and compensated for in this configuration. Two options are available here: Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 13: Ethernet/Ip Connection

    More information on this topic can be found in the technical literature and the applicable standards. Interference Electromagnetic fields can interfere with the communication path. Interfering signals caused by induction in parallel conductors Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 14 The same applies to galvanically isolated signals. However, unexpected results may arise in networks that are created by multichannel systems without isolation. This is because the filter capacitors may even run in parallel, depending on the setup. Isolate the channels to eliminate any interference. EMC filters in a network (simplified diagram) Rockwell Automation Publication 1719-IN001D-EN-E - November 2020...
  • Page 15: Additional Resources
