DB1000 Series Digital Indicating Controllers Download PS Sheet

The DB1000 and DB1000F are digital indicating controllers incorporating microprocessors giving them an outstanding performance including an indicating accuracy +/-0.1% and a sampling period of 0.1 sec for greater stability of control, the DB1000F incorporates a fuzzy logic circuit.
These controllers have a variety of features; multi-range inputs, 8 target values can be preset and a scaling function is provided as standard. Values are indicated by easy-to-read digital LCD displays; setting are input in the interactive mode while watching the dot-matrix LCD display. With these controllers, it is simple to realize a sophisticated, high-precision control system.
