The power output stages are directly connected with the temperature controllers. Only the PT1000 sensors and the heating coils need to be connected. No complex wiring between the controller and the heating controls is necessary.
The compact devices operate up to four independent heating circuits. For each heating circuit, a power output stage is available which can be placed under loads of up to 10 A.
Substantial savings potentials result due to the fact that many individual devices are no longer required, and to the simplification of the wiring.
