The Autonics TK4S-B2CR Temperature Controller is designed for rapid and accurate temperature regulation in critical processes. It operates on a dual-range power supply of 24VAC~ 50/60Hz or 24–48VDC and delivers fast control decisions through a 50ms sampling cycle. The unit supports multiple control methods including ON/OFF, P, PI, PD, and PID, offering exceptional flexibility for both simple and complex systems. With support for thermocouples, RTDs, and analog inputs like 4–20mA or 0–10V, it easily integrates with most industrial sensors. Its proportional band stretches from 0.1 to 999.9℃, while the integral and derivative time adjustments allow fine PID tuning up to 9999 seconds. Additionally, the controller supports manual reset and adjustable hysteresis for stable operation in dynamic load conditions.
Built with industrial-grade safety and durability in mind, the TK4S-B2CR features double reinforced insulation with a dielectric strength of 2kV, ensuring safe separation between the input and power circuits. Its IP65-rated front panel protects the internal system from dust and moisture, making it suitable for harsh environments. The 4-digit 7-segment LED display is bright and clear, providing real-time process feedback. With ±0.3% full-scale display accuracy and optional RS485 communication, engineers can monitor and configure systems remotely. Dual control outputs include a relay output (250VAC, 3A) and a current/SSR drive (DC 0/4–20mA) signal for flexible actuator connectivity. The lightweight form factor (approx. 150g) and easy parameter setup make it efficient to install even in compact panels.
The TK4S-B2CR is widely trusted in applications such as industrial ovens, packaging machinery, plastics molding, and lab heating systems. For junior engineers, the user-friendly interface makes it easy to configure and deploy, while senior technicians appreciate the robust PID tuning features and dual-output architecture. In training institutions, it’s used to demonstrate real-time feedback, sensor input scaling, and closed-loop temperature control. Whether you're automating a heater, controlling a dryer, or stabilizing thermal flow in a chemical process, this model adapts with ease.
