The excerpt you provided outlines the specifications and features of the tension electronics PFEA113, along with the associated load cells and junction box:

1. Tension Electronics PFEA113:
   • The PFEA113 is an advanced tension electronics unit designed to handle up to four load cells and provides six configurable analog outputs for control and monitoring of web tension.
   • It also offers output signals on Profibus-DP and features gain scheduling via digital input or Profibus for two different web paths, as well as zero set capability.
   • The unit includes self-diagnostic functions and four configurable digital outputs for alarms and level detection. Status of self-diagnostic functions is available on Profibus-DP.
   • It can be combined with up to three units to handle segmented roll applications, such as winders, with up to 12 load cells.
2. Load Cells:
   • Compatible load cells include PFCL 301E, PFTL 301E, PFRL 101, PFTL 101, PFCL 201, and PFTL 201.
3. Junction Box PFXC 141:
   • The system may utilize a junction box PFXC 141 for connecting load cells and tension electronics.
4. Installation Requirements:
   • The metal bottom of the PFEA113 unit connects to the metallic DIN-rail, serving as the earth connector for internal logic and ensuring EMI immunity and RF emission.
   • DIN-rails should be chromium-plated for corrosion resistance, and star washers should be used with each screw to fasten the DIN-rail to the mounting plate.
   • The minimum screw diameter for fastening the DIN-rail to the mounting plate is 5 mm, with a maximum distance between screws of 100 mm.
5. Application:
   • The equipment is intended for use in various manufacturing processes where web material, such as paper, plastic, or textile, is transported in a machine.
   • The force on the roll, proportional to the web tension, is transferred through bearing housings into the load cells, generating signals processed and amplified by the tension electronics for process control, display, or registration.

Overall, the PFEA113 offers comprehensive functionality and user-friendliness for precise tension control and monitoring in industrial applications involving web material processing.
