Front doors

• Versions:
  • Universal front doors for digital and analog I/O modules
  • Universal front doors for the interface module IM155-5 PN ST
• Included in the scope of delivery of the respective modules.
  Can be ordered as a spare part in a set consisting of five universal (unlabeled) front doors.
• Front doors for I/O modules: Universal labeling sheets and cabling diagrams are included. Cabling diagrams can be detached from preperforated sheets and inserted inside the door.
  

U connector

• To interconnect the modules (self-assembling backplane bus)
• Implementation of a rugged, interference-free station setup through
  • consistent separation of supply voltage of modules and data signals
  • fully shielded, gold-plated contacts for the data bus
• Included in the scope of delivery of each module. Available as spare part in sets of 5.
  

Shielding

• Components for implementing the integrated shielding concept of the S7-1500:
  • 24 V DC infeed element for supplying the analog module:
    strict separation of infeed and analog signals ensures high EMC stability.
  • Shield clamp for insertion in the front connector:
    allows a low-impedance connection and optimally dissipates interference.
  • Universal shield terminal:
    connects the cable shield with the shield clamp and is simultaneously used for mechanical fixing.
• Included in the scope of delivery of the analog modules. Available as a spare part in two versions:
  • Shielding set, comprising infeed element, shield clamp, and shield terminal (pack of 5 units each)
  • Individual shield terminals (pack of 20)
• No tool required for assembly/disassembly
