Controller / limiter combination

HT 41 / 42 series

As a result of their free configurability and compact design, the HT 41 / 42 self-programmable temperature controllers are universal controllers in machine, system and apparatus applications.

In the design of this device, particular attention was paid to the limiter function with a permanent shutdown for unattended operation according to DIN/VDE 0721 and to non-contact switching of 3680 Watt.
