ControllersIndicators Digital Indicating Controllers DB1000 Series Digital Indicating Controllers     The DB1000 series is 96 x 96mm digital controllers with the indicating accuracy of ± 0.1% and the sampling period of 0.1 second. These controllers have a variety of features including multi-programming function (8 kinds), universal inputs, scaling function as well as easy-to-read colored LCD displays and the interactive type settings with the dot-matrix LCD display. Features Indicating accuracy: ±0.1%; Sampling period: 0.1 second The high-performance microprocessor provides the indicating accuracy of ±0.1% and the sampling period of 0.1 second. Easy simple-mode operation By separating the parameters at the settings up through switching between the simple function mode and multi- function mode, the normal running is simplified. 8 kinds of setpoint By using the front-panel keys, 8 kinds of setpoint being programmed are freely selectable and independent PID constants can be set each setting value. Universal inputs Two types of universal inputs, the total of 34 inputs including 28 thermocouple inputs, 5DC voltage inputs and 1DC current input, or 12 resistance thermometer inputs, are prepared. Auto-tuning function The optimum PID constants can be calculated automatically by the auto tuning function. Versatile alarm function Four alarm points are available on each setpoint. High/low alarm and deviation/absolute alarm can be set independently on each alarm point. Universal power voltage The controllers are designed for 85 to 264VAC. CE (option) Models complying with CE are available.
