Certification of Operating System Version MOS83x V710.ECA7

The existing certificate was supplemented with the new:

  1. Operating system for the CPU 835-T/SIL:
    "MOS83x V710.ECA7"
  2. Safety-oriented digital extension module in accordance with Safety Integrity Level SIL 2:
    "DIT 735-Tx/SIL"

The following hardware and software modules meet the DIN standards: EN 61508, EN 50129, and EN 50128 in accordance with SIL 2 or SSAS2

  • CPU 835-T/SIL
  • Operating system MOS83x V710.ECA7 with PXROS-HR V6.1.1.2
  • DDT 735-Tx/SIL
  • DIT 735-Tx/SIL

New Safety Certification MAS 83x / MAS 73x SIL 2zoom
 
DIT 735-Tx/SILzoom

The DIT 735-Tx/SIL is a safe digital extension module for the CPU 835-T/SIL controller.

Through development in accordance with SIL 2, additional monitoring functions in the assemblies are implemented that can ensure a safe state at all times. DIT 735-Tx/SIL is designed for signal voltages from 24 to 36 V DC (version TG) or 72 to 110 V DC (version TV) and offers 24 secure digital inputs.


 

The new operating system for the CPU 835-T/SIL – the "MOS 83x V710.ECA7" – was certified according to EN 61508, parts 1 to 3 and EN 50128, SIL 2.
