6.1
Maximum Ambient Temperatures
Series N-132 devices can be used across a wide temperature range.
The maximum permissible ambient temperatures vary based on the device version
and installation condition.
6.2
Power Dissipation
The max. power dissipation in rated operation (output: 20 mA; auxiliary power: 24 V DC;
load = 250 W) is specified in the "Technical Data" chapter. In practice, not all devices are
operated at a full load. As a result, project engineering is usually performed at an average
power dissipation of 70 % (P
70%
).
