Enhance the performance of your PELCORE TEC controllers with precisely tailored accessory solutions. Whether for communication, signal conversion, or operation, our expansion modules are designed for seamless integration into your existing system architecture.
Seamless communication—regardless of your system’s underlying platform.
PELCORE Comm-Boards enable the integration of all common communication interfaces and ensure that you can reliably control and monitor your application at any time.
By default, PELCORE TEC controllers can be expanded with stackable Comm-Boards for serial communication. This enables straightforward communication via RS232, RS485, RS422, and UART without additional effort – both for precise control and the specification of setpoints for temperature and peripheral systems, as well as for continuous monitoring of your system.
Not enough yet? The PELCORE Comm-PRO Boards extend this functionality with an integrated web server and network-capable communication via a REST API.
In addition, all recorded parameters can be continuously logged and analyzed retrospectively. This ensures seamless traceability of your processes at all times.
Seamless conversion of control signals and voltage levels.
Do you have peripheral components that do not match the voltage level of your Peltier system, or do you want to integrate 0–10 V or 5–20 mA signals into your system? No problem!
y extending the PWR-CTRL TEC controllers with Converter-Boards from the PELCORE universe, control signals can be easily implemented and flexibly adapted to your specific requirements. This allows additional sensors, such as flow meters, to be connected, or 0–10 V control signals to be directly implemented as setpoints.
Power-supplying DC/DC converter boards also enable the expansion of your PELCORE TEC controller with additional peripheral components, without the need for extra power supplies.
Easy operation without integration effort
PELCORE TEC controllers enable flexible, application-oriented HMI solutions through a variety of display variants.
DNPT TEC controllers can be directly connected to membrane keypads and operated intuitively. In addition, 2.83″ displays can be individually configured and provide exactly the functions required for your application.
In combination with the Comm-PRO communication board, the integration of 2.83″ touch displays is also possible. This allows warnings, errors, and status messages to be reliably read out at any time.
Laser sources and the laser diodes within them require highly precise temperature control to ensure consistent performance. Even minor temperature fluctuations can affect the emitted wavelength and lead to uneven and unstable laser output. The use of Peltier modules or alternative cooling via fluid circuits ensures reliable and stable temperature management. This keeps the laser operating in its optimal range at all times—even in demanding continuous-use applications. Control is handled by high-performance TEC controllers that enable precise temperature regulation. Optionally, PELCORE TEC controllers are designed to integrate directly into existing laser control PCB designs via a PCI Express edge connector.
Thermocyclers and PCR systems precisely control temperature cycles of samples to amplify targets such as viruses and reach detectable concentration levels. This process requires highly accurate and dynamic temperature control, with rapid ramp rates of several degrees per second. At the same time, defined temperature limits within the sample must not be exceeded to ensure reliable and reproducible results. For complete process reliability, continuous monitoring and logging of all parameters is essential. Potential faults must be detected early and reliably prevented. This is where PELCORE TEC controllers come into play: with optimized control parameters, bidirectional Peltier control, and comprehensive monitoring with freely definable thresholds, they enable precise, fast, and reliable temperature management—even in the most demanding applications.
Modern gas drying systems are essential for the precise analysis of process gases, for example in the hydrogen and petrochemical industries. Only reliable gas conditioning ensures accurate monitoring of processes and early detection of critical states. Precise analysis is crucial to identify contamination or improper gas compositions in time, helping to prevent faulty processes—even in extreme cases involving explosive gas mixtures. At the core of gas conditioning is the dehumidification of the sample gas, for example using high-performance Peltier dryers. These bring the gas into a stable and reliably measurable state. The precise control of the integrated cold trap is handled by PELCORE TEC controllers. In addition to stable temperature regulation, they ensure a high level of process reliability: deviations and malfunctions are detected and reported in real time, effectively preventing undetected fault conditions.
The laboratory environment is one of the key application areas for thermoelectric systems. Both chemical and biological processes are highly sensitive to temperature changes, which can significantly influence analytical and development results. Many applications therefore rely on thermoelectric temperature control, as it enables precise bidirectional regulation (heating and cooling). This allows temperature conditions to be controlled accurately and ensures reproducible results. PELCORE TEC controllers not only deliver highly precise temperature control, but also exceptional flexibility. An integrated cycle management system enables fully configurable temperature ramps and complex thermal process sequences. In addition, the systems provide complete capture and documentation of all process data—an essential foundation for quality assurance, traceability, and regulatory compliance in laboratory environments.

2x PT100/PT1000 and 4x NTC sensors
The controller can monitor multiple temperatures and, via additional sensors, also track system operating conditions. These can be configured as warnings (signal output) or errors (system shutdown). When these thresholds are triggered is defined by the customer or the specific application.
Several interfaces are available, including RS232/485, UART, REST API, and web server-based control. Depending on the desired interface, the appropriate communication board must be selected (except for UART).
In case of errors, the controller responds according to the configured warning and error logic by shutting down or issuing user alerts. In the event of a power failure, the controller is not damaged if it is suddenly disconnected from power. It also retains its configuration. If an SD card is used, logged data remains preserved as well.
The controller is initially delivered without configuration and must be set up by the customer using software.
We can configure the controller according to customer requirements and, especially for repeat orders, deliver it consistently in the same configuration each time. Since the controller is highly powerful and offers extensive functionality, the initial setup must be carried out together with one of our technicians, who aligns the system with the customer’s application. Of course, the customer can determine their optimal configuration on their own system and subsequently send it to us for implementation.
Firmware updates are distributed by us and actively announced via email notifications. In the future, a dedicated section on our website will also be available, including an integrated SharePoint. Customers will be able to receive access to this platform.
