General Description

The RB Series is a high performance budget friendly temperature controller. Save space and save money with RB series that gives

outstanding control capability and comprehensive functions incorporated into a slim body case.

Applications include various plastic machines (extrudes, injection machine, etc), electric furnaces, semiconductor, food processing,

environmental chambers and many others.

Features

Easy-to-read with large 11-segment LCD display
The depth of 60mm
Sampling 0.25 sec
Brilliant II PID control
Start-up tuning and Autotuniung

Panel space saving : 60mm depth

The RB Series has very short depth.
The series was designed with a mounting bracket that allows

close horizontal mounting of as many as six units.

Calculates optimum PID values to stabilize
control faster than ever

The improved autotuning algorithm calculates optimum PID
values that shortens the time to reach stable control at the set
value as well as eliminating overshoot/undershoot.
The new PID algorithm also suppress overshoot/undershoot
against external disturbance.

SV

Startup tuning

Startup tuning eliminates time required for conventional
autotuning as it calculates optimum PID values by temperature
characteristics at start up.
It is useful in applications which require a long time for
conventional autotuning.
The timing of activation of start-up tuning can be selected from
at power-up, at setpoint change, and at power-up/setpoint
change. It is also settable to Only-once or always-ON.

Power ON

• Startup tuning function can be set ON/OFF.

• Heater power needs to be turned on simultaneously with or before turning on power to the
temperature controller.

• If startup tuning does not calculate suitable PID values due to characteristics of application,
use Autotuning function.

Easy parameter setup via USB loader port

The RB series has a standard loader port to connect to a PC
USB port via COM-K2 (USB communication converter).
Using Win-UCI software on the PC, parameter settings can be
easily saved on the PC in CSV format, and the same parameter
settings are easily copied to other controllers.

Easy Fine tuning with 6-level of control
response adjustment

After the PID values have been autotuned, the Fine tuning (FT)
function allows the operator to adjust the control response speed
with a 6-level adjustment parameter (-3 to +3) without changing

PID value.

Quick Start Code

• Quick start code 2 tells the factory to ship with each parameter preset to the values detailed as specified by the customer.
Quick start code is not necessarily specified when ordering, unless the preset is requested.
These parameters are software selectable items and can be re-programmed in the field via the manual.
