DB1000 SERIES DIGITAL INDICATING CONTROLLER
DB1000 SERIES DIGITAL
INDICATING CONTROLLER
The DB1000 series controllers are 96 × 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 parameters can be set each setting value.
• Universal inputs
Two types of universal inputs, the total of 34 inputs including 28
thermocouple inputs, 5 DC voltage inputs and 1 DC current input, or 12 resistance
thermometer inputs, are prepared.
• Auto-tuning function
The optimum PID parameters 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-marking (Option)
The models with CE-marking are available as an option.

With external make-contact signal, output is fixed at the preset value.
The speed of changing from the auto value to the preset value is limited by the output change limit of this option.
Setting range: Preset value 0 to 100%
Change limit value 0.1 to 100.0%
A unit converting alarm outputs from transistor outputs to relay outputs is available.
Output is maintained at the manual output condition by an external make-contact signal.
