Temperature derating
The temperature derating graph allows you to determine the maximum permitted tem
-
perature pairings of ambient and media temperatures in specific framework conditions
(typical conditions: U
v
= 24 V, Q1 = 10 mA, Q2 = 10 mA, Qa = 21.5 mA, Qb = 21.5 mA,
R
Qa
= 250
Ω
, R
Qb
= 250
Ω
).
If the medium temperature is rising to the value of 95 °C the maximum ambient tem
-
perature allowed is decreased accordingly the following diagram.
