The Autonics TK4H-14RN operates on a universal 100–240VAC~ 50/60Hz power supply and features a rapid 50ms sampling cycle to ensure real-time temperature feedback. This model supports advanced control algorithms including PID, P, PI, PD, and ON/OFF modes—giving engineers the flexibility to tune control loops precisely for both simple and complex thermal systems. With a sharp 4-digit 7-segment LED display, users can monitor process values with high clarity, even in dim panel environments. It supports multiple sensor inputs such as thermocouples (K, J, T, R, S), RTDs (Pt100Ω, Cu50Ω), and analog signals (4–20mA, 0–10V), allowing seamless compatibility with existing field instrumentation.
Engineered for robust industrial applications, the TK4H-14RN features a reliable relay output rated at 250VAC~ 3A, enabling direct actuation of heaters, alarms, or contactors. The front panel is IP65-rated, ensuring protection from dust and water splashes—ideal for food, pharma, and chemical processing lines. Internally, the device incorporates double insulation and a 2kV dielectric strength between input and power components, safeguarding equipment and operators from voltage interference. Display accuracy is maintained at ±0.3% F.S. at room temperature, while adjustable proportional band (0.1 to 999.9°C), integral time (up to 9999 sec), and hysteresis control offer tailored thermal responses. With optional digital and CT inputs, the controller can extend its function to energy monitoring and safety logic integration. Its lightweight design (~211g) makes it perfect for dense control panels without compromising on reliability or safety.
The Autonics TK4H-14RN is widely used in plastic molding machines, ovens, food packaging lines, chemical baths, sterilizers, and drying chambers. Its ability to maintain consistent temperatures helps reduce energy wastage and improves batch-to-batch quality. In the pharmaceutical and electronics industries, where tight thermal accuracy is essential, this controller ensures compliance and protects sensitive processes.
Maintenance engineers appreciate its intuitive configuration and sharp display, while panel builders value the slim form factor and IP65 protection for long-term operation. Engineering students and junior staff find it easy to understand, thanks to the clear parameters and stability in dynamic environments. Whether you're installing in a new production line or retrofitting a legacy system, the TK4H-14RN brings dependable performance, safety, and efficiency to any industrial control loop.
