Notes:
❇1This value can change due to the switching frequency, environmental conditions,
and desired reliability level, therefore it is recommended to check this with the ac-
tual load.
Conditions for oper-
–40°C to +85°C (up to 24 V coil)
❇2The upper limit for the ambient temperature is the maximum temperature that
can satisfy the coil temperature rise. Under the packing condition, allowable tem-
perature range is from –40 to +70°C –40°C to +158°F.
