The snap-on, digital controller modules is characterized by a compact construction. It is highly suitable for driving proportional valves and for controlling a preset pressure, volume flow or a position. Apart from the 24VDC-version, a 12VDC-version is available. The module is available as basic controller and as enhanced controller. The set-point position is preset externally (e.g., with a potentiometer). In case of the Enhanced controller, the set-point position additionally can be preset by means of freely adjustable traveling profiles. As actual value transmitters, analogue (in case of the Enhanced controller also digital -) measuring systems can be directly connected to the controller module. The Basic controller has a 10-bit -, the Enhanced controller a 16-bit resolution of the analogue inputs. The parametrization takes place through an USB - interface by means of a menu-controlled parametrization - and diagnostics software.
