The laboratory controller is preferably used for temperature control of heating plates, heating windings, temperature control baths and heating ovens in laboratory and production. The integrated compact controller meets a variety of technical requirements. It is operated, parameterized and configured with only four buttons in the splash-proof front panel. The space-saving ABS plastic housing has the dimensions B=180 mm, H=170 mm, D=200 mm. The compact controller, round connector for sensors, THE ON-OFF switch and the optical display for excess temperature are built into the front panel. The control outputs and fuses can be accessed at the rear. The front earthing contact socket-outlet (load circuit up to 10 A) is connected via a semi-conductor relay. It serves for contact-free switching of the load output, which avoids interference voltages as a zero voltage switch.This text is machine translated.
