S2DM30R

S2DM30 is a microcontroller based dot matrix display device for lifts. The fundamental idea behind the S2DM30 is having a considerably small 2-digit device, yet having almost all features that 3-digit models have. The audio feature is not available for it. It can be assembled either to the car or to a level. It can present floor markings, direction arrows and indicators. It accepts wide range of nominal supply voltages, because it is equipped with high efficiency switched mode power supply. Advanced digital filtering enhances robustness in poor signal quality environments.
