Easy Automatic Operation
The simple program ADF (AUTO-DRIVE FILE) is easily createdfrom the log. Not only can the controller be automatically controlled withthe free PC app, but the program can also be uploaded to the main unit andused autonomously. The startup ADF setting can also be used toautomatically operate immediately after startup.

Connect Diagram and Extensibility (Semi Custom, Full Custom Correspondence)
Provides power to drive the controller'scontrol circuitry. Power supply is mandatory.
A power supply of 5 to 24V is required. If it iswithin this range, it can be shared with thePeltier, AUX/DCO terminals using the jumper
plug provided free of charge.

With full customization (Housing and someboard changes required), it is possible tosupply up to 50V 30A, or add up to fourchannels of 50V 15A drive boards.
It is also possible to change to an evenlarger drive element.
The GND terminal is common to the otherpower supply terminals.

Fully customizable
and can connect to WiFi

As standard, it can output up to 50V 12A(minimum voltage 1V drive possible).
With full customization (Housing changesrequired), it is possible to supply up to 50V30A, or add up to four channels of 50V 15A
drive boards.
It is also possible to change to an evenlarger drive element.

System PowerSupply Terminal

AUX/DC OUTLET (DCO)
Power Supply Terminal

As standard, it can supply up to 50V 2A ofpower to DCO, AUX1, and AUX2 in total.
With full customization (Housing changesrequired), it is possible to change to an evenlarger power supply utilization board.

T1 Sensor Terminal
Peltier Power Supply Terminal

T2 Sensor Terminal

Any of the following sensors can be connected toT1 and T2 (If it is not used as a control sensor, it
can be set to be not connected).
●Pt100 (2, 3, 4 wire)●Thermocouple(K thermocouple, T thermocouple, etc.)●Thermistor (compatible with voltage drive, etc.)
It can be switched by DIP switch on the bottom orby command. By uploading and switching a tablecorresponding to each sensor, it can be used withvarious sensors.
Fully customizable (Housing changes required)and compatible with digital sensors.

WiFi

3-Wire RS232C Terminal (DB9)Peltier Output Terminal

As standard, a maximum output of 50V 2A
can be achieved with DCO (DC OUTLET),
AUX1, and AUX2 combined.
Semi-customization is supported, and AUX1
and AUX2 can also be taken out as open
collector outputs, allowing combinations witha variety of drive elements and modules.

DCO Output Terminal

USB-C Connector

AUX1 Output Terminal
AUX2 Output Terminal

It can be connected to a PC or PLC with an RS232C
terminal (DB9), and can also be connected tovarious devices via various protocol conversion
adapters. It is possible to connect to the free
Windows control application, and the control
commands to the main unit can be monitored by thecontroller simultaneously with USB-C (commands
cannot be sent simultaneously), and operation suchas Peltier drive status can be confirmed on the mainunit monitor.

It can be connected to a PC etc. with a USB-C
port. It is possible to connect to the free Windows
control application, and the control commands tothe main unit can be monitored by the controller
simultaneously with RS232C (commands cannot
be sent simultaneously), and operation such as
Peltier drive status can be confirmed on the main unit
monitor.The USB-C port power supply is isolated
from the main unit.

Temperature display, graph display, device control and setting input with 3.5 inch TFT touch screen.
Various operations are possible using the free app (compatible with Windows 7/10/11).
(Fully customizable) Connect via WiFi using the built-in WiFi server, controllable from a PC with abrowser (Win, Mac, Linux), tablet (including iPad) or smartphone (iOS and Android), and can belinked to the cloud.
Display language can be switched between Japanese and English.
Supports PID control, P control (Ki, Kd values are set to 0), and PI control (Kd value is set to 0).
ON/OFF control (using the app or the built-in AUTO-DRIVE).
Open loop drive by direct input of PWM value (using the app or the built-in AUTO-DRIVE).
Supports high frequency temperature setting change control (using the app or the built-in AUTO-DRIVE).
Kp, Ki, and Kd can be entered in 0.001 increments.
AUTO tuning support Automatic input for Kp, Ki or Kp, Ki, Kd.
In addition, various parameters for AUTO tuning can be changed.
PWM drive or ON/OFF drive
Supports Pt100 (2, 3, 4 wire), thermocouple (K), and thermistor (supports Ref. voltage and ratiometricmeasurement, reference resistor connection is required for all thermistors ) as standard. Also, byassigning a sensor table to each sensor, high accuracy measurement is possible. Using the sensor table,
it supports thermocouples other than K and various thermistors other than 10k. All settings can be madeby the user. Fully customizable, it supports digital sensors via I2C connection.
External temperature information can be used as the control temperature.
"No sensor" setting is possible regardless of whether a channel other than the control channel isconnected. Control is possible using Tcalc, which is calculated based on temperature information fromtwo channels (VCP: Virtual Control Point).
Equipped with multiple features such as measures to prevent runaway due to disconnection of a sensor.
Also, with full customization, additional safety measures such as detection of abnormal temperaturerise of Peltier units using thermistor temperature measurement are possible.
Operation management of the main unit setting screen with PIN is possible.
Equipped with Auto-Drive File (ADF), a proprietary macro automatic control method, it supports allcommands available on TA-PB-2, as well as branching when temperature threholds are reached andrepeated operations. Logs created using the free PC app can be edited with a text editor or spreadsheet
software. They are then loaded the PC app for verification, and then uploaded almost as is to the main
unit with the push of a button, enabling automatic operation on the main unit. It is also possible to set
the ADF to run automatically with the start-up of the main unit. With this function, programming
knowledge is almost unnecessary for automatic operation.
