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)
