Multiple channel control for positioning elements

摘要

The controller has a processor (1) comprising an input to receive input parameters and two outputs for two control channels (6). The channels are controlled independently, and have voltage-dependent control elements (5) i.e. expansion elements, that are supplied with voltage independently of each other and/or are monitored. A transformer (21) is electrically connected with a power supply (2) and provides a predetermined nominal voltage of the control element, where the channels comprise a Triode for Alternating Current Switch(TRIAC)(RTM: Electronic three terminal device) (4).
