Description

Classification of the safety-related parts of a control system in respect of their resistance

to faults and their subsequent behavior in the fault condition, and which is achieved

by the structural arrangement of the parts, fault detection and/or by their reliability.

The categories are: B, 1, 2, 3 and 4. (EN ISO 13849-1)

Common cause failure (%) (EN ISO 13849-1)

Frame size designation of the diode supply module

Diagnostic coverage (EN ISO 13849-1)

Failure in time: 1E-9 hours (IEC 61508)

Physical size of the drive or power module

Hardware fault tolerance (IEC 61508)

Insulated gate bipolar transistor

Average probability of dangerous failure on demand (IEC 61508)

Average frequency of dangerous failures per hour (IEC 61508)
