The CAL 9400 is a 1/16 DIN dual-display autotune temperature controller designed for precision thermal management in industrial, manufacturing, and scientific environments. This compact unit delivers PID control with integrated autotuning and derivative approach control (dAC) to minimize overshoot, supporting heat-only, heat/cool, or ON/OFF operation modes. The dual 4-digit LED display with status indicators provides real-time process and setpoint visibility, while menu-driven configuration ensures rapid commissioning without external software.
