Temperature Controllers
The self-programmable temperature controller HT 41 / 42 is a
universal controller due to its free confi gurability, its optional serial
interface and the compact design for machine building, plant and
apparatus construction.
Particular attention was given to the limiter function during the de-
sign of this device, with a permanent shutdown for unintentional
operation according to DIN/VDE 0721 and on the high non-contact
switch capacity of 3600 Watts.
