Precision Control Starts with the B41
Fast response, flexible outputs, reliable communication
The B41 Board PID Temperature Controller combines fuzzy logic, dual outputs, and Modbus RTU to deliver fast, stable, and intelligent process control. Designed for embedded systems, it supports multiple sensor types, auto-tuning, ramp/dwell timers, and digital filtering. Dual outputs can be configured independently for heating, cooling, or alarms, while bumpless transfer ensures seamless operation during sensor faults. With 18-bit input resolution and 15-bit output accuracy, the B41 is the compact powerhouse for OEMs and system integrators.
High-Precision Sensor Input Compatibility
Supports multiple signal types for reliable measurement
The B41 Board PID Temperature Controller offers broad input signal support, including thermocouples (J, K, T, E, R, S, B, N, L), RTDs (PT100 DIN/JIS), and linear inputs such as 0–60mV, 0–10V, and 4–20mA. Its 18-bit ADC delivers high-resolution process value acquisition, while programmable filtering ensures signal stability. This makes the B41 ideal for applications requiring precise and consistent temperature or process monitoring across different sensor systems.
Flexible Output Control Options
Relay, SSR, analog, and alarm output in one compact board
The B41 controller supports versatile output configurations, including relay contact, solid-state relay drive (SSR), and isolated analog output (voltage or current). Dual independent outputs allow for heat/cool control or alarm functions, while a third output can be configured as a dwell timer or additional alarm. With a 15-bit DAC for accurate analog signal generation, B41 ensures seamless integration with actuators, PLCs, and external systems in temperature-critical environments.
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.
