DB2000 SERIESDIGITAL INDICATING CONTROLLER
The DB2000 series is a 96×96mm digital indicating
controller with the indicating accuracy of ±0.1% andthe control cycle of approximately 0.1 seconds.
The configuration of highly functional system isenabled by various options including 2 transmission
signal outputs, 2 communications ports andarbitrarily-allocation of digital inputs.

 FEATURESz Large easy-to-view 5-digit 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.
z Highly-functional operation screen and settings
screenThe controller inherits the operation screen and thesettings
screen adoptingtheLCD(liquidcrystal-display) which has been familiarized for longtime. Furthermore, the screens have become
high-definition and highly sophisticated.

z READY function provided
Although the DB2000 series is the constant value
controller, switching to the state (READY) that any
control is not wanted is enabled.
In addition, the output value (MV) at READY can be
set arbitrarily.

z Outstanding controllability
Two types of PID algorithms, the position-type PID
algorithm and the speed-type PID algorithm, havebeen installed. You can select the optimum PID
algorithm for an object controlled.

z DI arbitrarily-allocation
When
thedigital
input
(DI)
is
added,
arbitrarily-allocation for assigning functions to those DI'sis enabled. It is the function enabling allocations suchas [READY/RUN] to DI1 and [Manual output
operation/Automatic output operation] to DI2.

z Versatile control functions provided
Versatile control functions, such as the automatic PID
system, which executes control by PID parameterspreset at every SV sections, and selection of the
2-output control system from PID system and split
system for 2-output types, are available.
z Communications 2-port type provided
Models with 2 communications ports are available. In
addition, speeding up and highly-functionalization ofcommunications have been realized. For example,
you can use 1 port for high order communications witha personal computer and another port for thecommunications remote (digital remote) function. The
communications protocol can be arbitrarily selectedfrom [MODBUS] and [PRIVATE].
z Transmission signal 2-output type available
2 types of transmission signal output, thehigh-precision type (0.1% of full scale) and the general
type (0.3% of full scale), are available. Transmission
signal 2-output types with these 2 transmission signal
outputs and models with transmitter power supply areavailable.

z Heater disconnection alarm
The heater disconnection alarm can be added to
ON-OFF pulse types or SSR drive pulse types only.

By connecting the designated CT externally, the current
value of heater is measured and can be indicated on
the operation screen.
z Other functions
Various functions including multiple auto-tuning, timer
function using the digital input (DI), control loop
abnormality alarm and user calibration are built-in.
z Conforming to international safety standards andEuropean directives (CE)The controller is in conformity with European directives(CE), and is UL and c-UL approved.
z Conforming to RoHS
The controller is an environmental consideration
product which does not contain directed hazardous
substances such as lead, etc.
