1 The required input voltage value (e.g. 24 V) should be added to the type designation: .. ICR 1-1212-N changes to 24 ICR 1-1212-N
2 See Block Diagrams
3 The output current of one output may be increased by 25% if the output current of the other output is reduced by 25% simultaneously.
Example for a 5 IWR 1-1515-N: The +15 V output current of 33 mA may be increased to 41 mA if the –15 V output current is reduced
to 25 mA.
4 The output current of both outputs of the 12, 24, 28 and 48 V input types may be increased by 20% of Io nom. Note 3 is applicable at
the same time. Example for a 24 IWR 1-2×1212-N: Io1 = +29 mA/–19 mA, Io2 = +19 mA/–29 mA or Io1 = ±19 mA, Io2 = ±29 mA
5 Only standard temperature range N or option T available
