Derating
The three derating curves are valid at 100% simultaneity of the relay outputs.
A distinction is made between contacts 13/14 and 23/24.
Use only one diagram to determine the derating of the safety module.
Example (derating 1):
If contacts 23/24 are loaded with 6 A at T
A
= 50°C, then contacts 13/14 can
only be loaded with a maximum of 2.6 A.
