All models when installed as FISCO Ta= -50°C to 45°C
Operating range is always limited to -40°C for all transmitters.
Models with CCoE, SAEx, KOSHA, NEPSI, INMETRO, or EAC TR-CU nameplate are limited to
temperature class T4 for all ambient and process temperature ranges. At the time of writing, only
CSA, FM, IECEx, and ATEX models have been certified with the temperature classes T5 or T6 as
specified in the table above.
