Carel Panel Mount PID Temperature Controller, 2 Input, 2 Output, Analogue, 230V, Auto-tuning IR33

The Carel IR33B7LR20 is a versatile panel mount PID temperature controller designed for precise management of temperature in industrial automation and process control applications. Featuring two analogue inputs and two outputs, this controller is well-suited for integration into complex systems where reliable regulation and digital communication are essential.

With a 230V maximum supply voltage and wide voltage compatibility (up to 250V), the controller ensures robust performance in a variety of environments. The auto-tuning PID control capability offers vital accuracy and automatic adaptation to changing system requirements, minimizing overshoot and stabilizing temperatures more effectively than standard controllers. This makes the IR33B7LR20 suitable for use in applications requiring sustained temperature stability, such as HVAC units, laboratory incubators, refrigeration systems, and manufacturing process lines.

The device provides an easy-to-use LED display with large control buttons, simplifying setup and operational adjustments in field conditions. Remote and programming key options enable quick configuration, making the controller a favorite for both commissioning engineers and long-term operators. Its panel mount design, with dimensions of 76.2mm length, 34.2mm width, and 94mm panel depth, allows for installation in control cabinets where space is at a premium. IP10 and IP65 ingress protection ratings ensure resilience to dust and water ingress under general industrial use.

2 analogue inputs and 2 outputs for flexible application coverage. Auto-tuning PID control for optimized process accuracy. LED display and intuitive user interface for status monitoring and adjustment. RS485/Serial digital communication for reliable system integration.

Compliance with international CE and EMC safety standards. Robust construction for industrial and laboratory deployment. Option for remote control and programming key enhances configuration efficiency.

Typical industrial use cases include incorporation into process control panels, refrigeration monitoring, laboratory automation, environmental chambers, and other temperature-sensitive systems in areas such as manufacturing, R&D, food processing, and water treatment. The IR33B7LR20 is engineered to provide consistent performance and adaptability across a spectrum of automation scenarios.

This product is supplied as a single controller unit. Compatible remote controls and programming keys are available separately for expanded functionality, ensuring integration flexibility for advanced industrial environments.
