ACU DIN controller

900.00zł net

ACU controller DIN is a fully functional controller designed for automation systems controlling the operation of supply and exhaust air handling units.ACU controller DIN can be installed in a control cabinet in a simple, intuitive way, as it is compatible with the DIN-type mounting rail standard. Peripheral components are connected to the controller, which is the central unit, through detachable terminal strips. The enclosure has clear descriptions consisting of a letter symbol, numbering and a graphic element indicating the nature of the connector. With this solution, the user saves space and time.

*To the ACU controller. DIN 4 devices controlled by analog signal can be connected. This is possible because one of the analog outputs - Y2 - can operate 2 devices (heater and cooler). The required condition is that they are not switched on at the same time. The COOL output is used for this, where Y2 is switched between the two terminals of this output for the heating or cooling sequence, respectively.
