About the TEC-8A-24V-PID-HC-RS232 Programmable Temperature Controller

The TEC-8A-24V-PID-HC-RS232 controller makes it possible to control temperature in the range of -70 to 70 degrees Celsius. The controller provides convenient parameter adjustment and reading capabilities through the UART port.

With its versatile functionality, this controller offers both heating and cooling capabilities without the need for jumper configuration. Additionally, it includes an open collector output, allowing it to serve as a signal for other devices. Clear LED indicators provide visual feedback on the heating or cooling activity.

Designed with compact dimensions, user-friendly regulation, and versatility, this controller finds widespread application across various industries. It is specifically designed to work with 12 V Peltier modules, but is compatible with modules operating within the 5 to 24 V supply voltage range.

Operating in PWM mode (Pulse Width Modulation), the controller is capable of handling currents up to 8 A. It utilizes the 10k NTC B3950 temperature sensor, and the default temperature setpoint is configured at 20 degrees Celsius.

Thanks to the adjustable PID controller parameters, this driver can be adapted to suit nearly any system. Depending on the system's inertia, a properly calibrated driver ensures precise temperature maintenance with an exceptional accuracy of up to ±0.05 degrees Celsius.

Recommendations and requirements

  • TEC-8A-24V-PID-HC uses serial port (COM) for PC communication. Various desktop applications such as RealTerm (Win), Minicom (Linux) or PuTTy can be utilized for data reading, writing and parameter configuration.
  • We recommend the use of power cables with a minimum cross-section of 0.5 mm2
  • The Peltier module's current depends on the supply voltage used. Common modules typically operate at 12-15 V, with the maximum current specified by the module symbol. For example, "12708" indicates a voltage range of 0-12 V and a maximum current of 8 A.


This temperature controller has no reverse polarity protection. Reverse polarity at the power supply will permanently damage the temperature controller.

If the temperature is higher than 70 degrees Celsius or lower than -70 degrees Celsius, the driver will not power the Peltier module. Additionally, the open collector output is grounded.




Achieve accurate temperature control with the advanced features of this controller.



With its user-friendly interface, the temperature controller allows for easy adjustment and monitoring.



I can fine-tune it to perfectly suit my system's needs.


Converted a TE Wine Cooler to an Incubator

Works great. I frequently send new set points over serial port. This operation occasionally failed. Tech support was prompt and helpful. Noise from my power supply was causing the problem. Now running TEC logic on separate power supply.


easy to use OEM TEC

I am using these for various temperature regulation tasks in prototype laser setups. These are perfectly well suited for this task.
