Fuji PXR3 Temperature Controller: Compact, Powerful, and Easy to Use

When it comes to precision control for temperature and process applications, the Fuji PXR3 Temperature Controller stands out as an advanced, compact solution. With its 1/32 DIN size (24×48 mm), the PXR3 is engineered for versatility in a wide range of industrial and OEM environments, combining powerful features with user-friendly operation.

Advanced Control Features

The Fuji PXR3 takes temperature control to the next level with its self-tuning capability—a major innovation in the process control industry. Unlike traditional auto-tuning, the PXR3’s self-tuning feature automatically re-tunes the controller in real time under specific conditions, ensuring consistent and precise performance without user intervention.

Additional control options include:

  • PID plus self-tuning for stable, accurate control
  • PID plus fuzzy logic for robust performance even in complex processes
  • Auto-tuning for easy initial setup

Flexible Input and Output Options

The PXR3 is designed to accept a variety of inputs, including thermocouple, RTD, and analog signals (4-20mA/0-5V), making it adaptable to a wide range of process needs. Outputs can be configured as:

  • Relay
  • SSR driver
  • 4-20mA

With single or dual output options, the PXR3 can handle multiple control tasks simultaneously.

Ramp/Soak Programming

For complex temperature or process profiles, the PXR3 offers an 8-segment ramp/soak feature, which can be expanded to 16 steps by linking two 8-segment patterns. This makes it perfect for applications like heat treatment, kilns, or environmental chambers.

User-Friendly Design

  • Large, bright LED display for easy reading in all lighting conditions
  • NEMA 4X waterproof faceplate (IP66 equivalent) ensures durability in harsh environments
  • Simple 3-button keypad for fast and intuitive programming
  • Screw terminals on the back panel eliminate the need for additional sockets, reducing installation costs

Connectivity and Software

With the RS485 communication option, you can monitor up to 31 PXR series controllers simultaneously using the industry-standard Modbus protocol. The PXR3 comes with free Windows-based PXR-LITE software, allowing for:

  • Easy programming from a PC
  • Real-time data monitoring
  • Trend graph visualization
  • Data logging to text files

Additional Options

  • Remote Setpoint Option for external control
  • Analog Retransmission Option for integration with other systems
  • Digital Input Option for external triggers
  • Timer Function for process automation
  • Heater burnout alarm option for safety and maintenance alerts

Built to Last

The PXR3 is manufactured under ISO 9001 quality standards, UL873 approved, and backed by a 3-year warranty—delivering confidence and reliability for every application.
