R22 PID Temperature Controller

Slim and Powerful DIN Rail Control

Universal input, dual output, USB config, and RS-485 support

The R22 is a compact and cost-effective PID temperature controller designed for space-limited control panels. Featuring a 22.5 mm DIN-rail mount, the R22 offers universal input support—thermocouples, RTDs, voltage, and current—paired with fast 200ms sampling and high-resolution 18-bit conversion. With dual output configuration, RS-485 Modbus RTU communication, and a micro USB setup port, the R22 provides reliable and flexible control in OEM, lab, and machinery applications. Whether used as a standalone device or integrated into complex systems, the R22 offers precision and performance in a minimal footprint.


Slim Control Interface for Easy Access

4-key layout with logical navigation for quick setup   

The R22 features a compact front panel with a clearly arranged 4-key keypad, optimized for fast operation in tight DIN-rail environments. The buttons are positioned for logical navigation through settings, allowing easy access to parameter configuration, alarm reset, and mode switching. Despite its narrow 22.5 mm form factor, the controller’s front interface ensures smooth interaction and reduces training time. Visual status indicators assist in verifying output and alarm states at a glance, enhancing confidence during installation and adjustment.  

High-Brightness Multi-Color LCD Display

Color-coded visual alerts for clear and safe operation  

The Core Series features a high-brightness LCD screen with multiple color indicators, enhancing visibility in various lighting conditions — even under harsh industrial environments. Each color is intelligently assigned to represent key system statuses such as normal operation, alarm, or output activity, allowing operators to identify conditions at a glance. Whether viewed on-site or from a distance, the display ensures quick recognition, reduced errors, and improved response time.

Universal Input for Various Sensor Types

Supports thermocouple, RTD, voltage, and current inputs  

The Core Series  controllers support a wide range of input types, including thermocouples (J, K, T, E, etc.), RTDs (PT100 DIN/JIS), voltage (0–10 V), and current (4–20 mA) signals. This universal input design makes them compatible with most industrial temperature sensors, ensuring flexible integration across different applications. 

Flexible Output Options for Control and Alarms  

Relay, SSR, and analog output available

Core  Series models offer versatile output options, including relay contact, SSR drive (pulsed voltage), and analog output (4–20 mA or 0–10 V). Depending on the model, up to two output channels can be configured for control or alarm functions. Optional features like CT input and event input further enhance system responsiveness and integration.  

Fuzzy PID Technology   

Smarter Control with Less Overshoot and Faster Response  

Fuzzy logic is combined with traditional PID control to deliver smarter and more adaptive temperature regulation. Unlike standard PID controllers that require manual fine-tuning for each application, fuzzy PID dynamically adjusts control responses based on real-time process behavior. The result is faster stabilization, reduced overshoot, and improved resilience to disturbances—ideal for processes where precision and speed are critical.

Built-in Programming Port for Fast Configuration

Micro USB interface streamlines setup and firmware upgrades  

The Core Series is equipped with a built-in micro USB programming port that allows users to configure parameters and update firmware directly from a PC. With the optional USB configuration cable and dedicated software, engineers can complete setup in minutes—without powering the device through system wiring. This feature greatly reduces installation time, simplifies maintenance, and ensures flexible deployment across various projects.

BC-SET Pro Configuration Software

Easy parameter setup and firmware upgrade for Core Series controllers

BC-SET Pro is the official configuration software for BrainChild’s Core Series temperature controllers. With a user-friendly interface, it allows engineers and technicians to configure parameters, copy settings between devices, and perform firmware upgrades via USB connection. The software supports offline setup and can store multiple configuration files, making it ideal for OEM production lines, system integrators, and field engineers.

Batch Read/Write for Multiple Controllers 

BC-SET allows users to connect multiple controllers of the same model and perform batch parameter read/write by defining a node address range. This feature significantly streamlines configuration in OEM or multi-device environments.

Clear and Accessible System Menu 

The system menu offers quick access to key operations like Rescan (F5), Read Data (F6), Write Data (F7), Write Multiple (F8), and Communication Settings (F9). Built-in hotkeys support fast, efficient navigation.

Intuitive Communication Setup Interface

The communication settings window lets users define COM port, baud rate, parity, data bits, and stop bits — with a “Default” button for quick reset and “Save and Exit” to finalize setup. Designed to reduce setup errors.

Visual Profile Editor for Programmable Controllers 

For controllers with profile functionality, BC-SET provides a graphical editor to configure temperature ramp/soak segments. Users can easily read, modify, and write profile parameters for precise thermal process control.
