MA900/MA901
The MA900 controls up to 4 channels, while the MA901 controls up to 8 channels in a compact 1/4 DIN size. The MA901 increases zone density and makes smaller numbers of loops affordable, yet still holds many of the advantages that a single loop controller might offer. This unit will aid designers of control equipment by saving labour costs, installation costs, electric panel sizes, and operation costs.
