IEC 61508
IEC 61508 covers functional safety of safety-related systems
that use electrical and/or electronic programmable electronic
technologies.
The standard aims to enable technological developments
to take place within an overall safety framework and to
provide a technically sound, system-based approach, with
sufficient flexibility for the future.The challenge is to
design the system in such a way as to prevent dangerous
failures or to control them when they arise.
TTControl I/O control units TTC 200 and TTC 100 were designed
to comply with the IEC 61508 international standard. The
stand-alone version and the network version with TTP fulfill
SIL 2 (Safety Integrity Level) and SIL 3 requirements respectively.
