The GOcontroll Moduline IV offers precise temperature, humidity, and airflow control for advanced R&D climate chamber applications.

Consistency is key in research and development testing. The GOcontroll Moduline IV delivers precision, flexibility, and repeatability for R&D Climate Chamber Control, managing temperature, humidity, and airflow across single or multi-zone setups. Its modular I/O architecture supports heaters, chillers, humidifiers, fans, and a wide range of sensors, enabling complex environmental profiles for material testing, electronics burn-in, and endurance validation. Designed for accuracy and scalability, the Moduline IV brings laboratory-grade control to everything from benchtop units to walk-in test chambers.

Modern R&D chambers demand programmable test conditions that mimic real-world environments. The Moduline IV executes custom temperature and humidity profiles with high timing precision using its real-time embedded Linux system. Engineers can design:

• Ramp/soak profiles for controlled heating and cooling.

• Step or cycle sequences for accelerated stress testing.

• Diurnal or seasonal simulations for long-term reliability studies.

• Custom control scripts created in MATLAB Simulink or Node-RED.

These test routines can be stored, versioned, and recalled easily, ensuring repeatability across experiments. Automated limits, alarms, and recovery logic safeguard samples during unattended operation.

The Moduline IV’s computing platform supports multiple independent PID control loops, allowing precise regulation of temperature, humidity, and airflow—each tuned to its own setpoint and sensors. This structure enables:

• Zone-specific temperature control, maintaining uniform gradients.

• Active humidity balancing through humidifier and dehumidifier management.

• Dynamic airflow or pressure adjustment with variable-frequency fans.

Real-time execution ensures stable control, even under rapidly changing conditions such as fast temperature ramps or airflow transitions. Multi-zone coordination allows one controller to manage several environmental chambers simultaneously or multiple sections within a single system.

Accurate and stable feedback is critical in environmental testing. The GOcontroll 6-channel input module gives engineers high-resolution, configurable sensor inputs for monitoring all key environmental variables. Each module supports up to six sensor channels, compatible with:

• Thermistors for temperature measurement.

• Humidity and dew point sensors for moisture measurement.

• Airflow and pressure transducers for circulation and sealing tests.

Multiple input modules can be combined to capture detailed temperature and humidity gradients throughout the chamber. Advanced sensor fusion techniques—such as averaging or weighted feedback—help maintain uniform conditions. The on-module signal conditioning minimizes noise and latency, ensuring stable and repeatable control.

Stable and responsive climate control depends on reliable actuation. The GOcontroll 6-channel output module provides up to six individually addressable outputs, designed for direct control of heating, cooling, and air circulation equipment.

Each channel supports:

• Digital on/off control for relays, solenoid valves, and heaters.

• PWM (Pulse Width Modulation) output for proportional power control of fans or resistive heating elements.

This flexibility enables smooth transitions between heating and cooling phases while maintaining tight environmental control. By combining multiple output modules, engineers can manage complex systems with multiple heat sources, circulation zones, or humidification paths.

When paired with the 6-channel input modules, these outputs form a fully closed-loop control system, providing accurate feedback-based regulation across all environmental parameters. The modular structure allows scaling from a single benchtop chamber to multi-zone R&D installations—all with the same controller architecture.

The Moduline IV offers built-in data logging and network connectivity for traceable, collaborative research. Timestamped logs, batch IDs, and recipe versioning make it easy to reproduce test conditions and verify results. Through Ethernet, CAN, or Modbus TCP, multiple chambers can be networked, allowing centralized supervision and integration with LIMS or MES systems.

Safety is embedded into every function. Over/under-temperature protection, door interlocks, and power-loss recovery ensure secure operation during long endurance tests. The modular IP-rated hardware withstands high humidity, vibration, and thermal cycling—ideal for industrial R&D environments.
