DB600 SERIES

DIGITAL INDICATING CONTROLLER
The DB600 series is a digital indicating controller with the
indicating accuracy of ±0.1% and the control cycle of
approximately 0.1 seconds.
Various functions including universal input and multiple
setting values (8 types) are provided as standard.
There are three types of size.
DB670 --- 96 x 96mm, DB650 --- 96 x 48mm,
DB630 --- 48 x 48mm

FEATURES
Excellent control performance
PID control algorithm and Z control algorithm are selectable according to the application.
PID control algorithm: Conventional control method
Z control algorithm: Our new algorithm (patent pending) which
has evolved the PID control method. Especially, the effect can
be expected such as overshoot suppression and speedy recovery in the event of disturbance control (during opening and
closing of the electric furnace).

24V power supply voltage type available
The power supply voltage 24V (AC/DC) type, which is advantageous in respect of safe, is available.
Various operating status in one glance
Operating condition
Setting value ramp (option for program model)
Analog bar output

Large easy-to-view 5-digit 11 segments display
Process value (PV) and set value (SV) are displayed by large
easy-to-view 5-digit display indicators. The resolution of 0.1 C
is enabled for more than 1000 C.

Universal input
Various measurement ranges of DC voltage (up to maximum
10V) inputs, DC current input, thermocouple inputs and resistance thermometer inputs have been built-in.

Highly-functional operation screen and settings screen
The controller inherits the operation screen and the settings
screen adopting the LCD (liquid-crystal-display) which has
been familiarized for long time. Furthermore, the screens have
become high-definition and highly sophisticated.

Program Operation (option)
Set 4 patterns, 12 steps.

Operability inheriting previous models
The controller inherits the settings screen which has been familiarized for long time. You can set up it with operation which is
not different from previous models. The performance of touching-keys has been improved and the outstanding operability
has been realized.

What is Z control?
Z Control is applied from control algorithm of skunk cabbage (white
arum ).
Skunk cabbage is a plant that generates heat to maintain body temperature at about 20 in spite of changes in the outside temperature.
Incorporating system of heating control by minimum energy to the controller.

Conforming to international safety standards and European directives (CE) (conformity pending)
The controller is in conformity with European directives (CE),
and is UL and c-UL approved.
Engineering Software (Standard attached)
By connecting to PC with exclusive USB engineering cable
(RZ-EC3) (sold separately), you can load / save parameter
data and acquistion.

Excellent control
Control algorithm (PID control, Z control)
You can choose the control algorithm PID control and Z control depending on the controlled object or application.

PID control
Conventional control algorithm

Z control
It is our original control algorithm which we evolved from general PID control.
Especailly during heating control, it can suppress overshoot effect, shortening stabilzaiton time, speed up of returing speed from distrubance (ex. the opening and closing of the oven door).

Achieve better control condition by new auto-tuning
Improved conventional auto-tuning and determine more appropriate control parameter setting.
Compared to the conventional method, it can suppress overshooting and deduct of the settling time.
