for RS40 types.
Environmental class and temperature code for types RS20 and RS30:
T4: 0 °C ≤ Ta ≤ +60 °C for "S" types
(Item 14 in the schematic legend) or
T4: −40 °C ≤ Ta ≤ +70 °C for "T" or "E" types
(Item 14 in the schematic legend).
Environmental class and temperature code for types RS22 and RS32:
T4: −40 °C ≤ Ta ≤ +70 °C for "T" or "E" types
(Item 14 in the schematic legend) or
T4: 0 °C ≤ Ta ≤ +50 °C for "S" types
(Item 14 in the schematic legend) or
Environmental class and temperature code for RS40 types:
T3: −40 °C ≤ Ta ≤ +70 °C for "T" or "E" types
(Item 14 in the schematic legend) or.
T4: −40 °C ≤ Ta ≤ +60 °C for “T” or “E” types
(item 14 of nomenclature breakdown).
T4: 0 °C ≤ Ta ≤ +60 °C for “S” types
(item 14 of nomenclature breakdown).
The modules shall be installed in a suitable enclosure in accordance
with EN 60079-15 providing a degree of protection of at least IP54
according to EN 60529, taking into account the environmental
conditions under which the equipment will be used.
