1)
Only applies for devices with ATEX marking
2)
If a switching current > 300 mA is switched via the relay outputs, low
current (V 10 mA) can no longer be reliably switched owing to erosion of
the gold contacts.
3)
It is to be ensured that current and voltage are selected such that a
switching capacity of at least 50 mW is reached.
