The Autonics TK4W-14RN High Performance PID Temp Controller is engineered to provide stable, high-speed temperature regulation for complex process systems. Backed by a universal 100–240VAC~ 50/60Hz power supply and a fast 50ms sampling cycle, it ensures minimal lag in feedback and response, allowing rapid adaptation to process changes. With five control methods—ON/OFF, P, PI, PD, and PID—engineers have the flexibility to configure the unit for both simple and advanced control loops.
Input compatibility includes a wide array of signals: thermocouples like K, J, R, S, and B; RTDs such as Pt100, JPt100, and Cu50; and analog inputs like 4–20mA and 0–10V, offering integration across legacy and modern control systems. The controller delivers a display accuracy of ±0.3% F.S. for analog and RTD signals, and ±5% F.S. for CT inputs, ensuring confidence in displayed values. The built-in relay output (250VAC~ 3A) supports load switching, while IP65 front protection shields the unit from dust, steam, and oil splashes—making it ideal for rough plant conditions.
It includes features like adjustable proportional band (up to 999.9%), integral and derivative time (up to 9999 seconds), and manual reset for fine PID tuning. Engineers can also benefit from the option to connect CTs or digital inputs for extended functionality. Designed to operate between -10°C and 50°C, and store safely from -20°C to 60°C, the controller remains reliable even in high-humidity (up to 85%) environments. The compact 211g design fits easily into standard control panels without sacrificing power or precision. Built with double insulation and 2kV dielectric strength, this model provides long-term electrical safety, helping users maintain uptime with minimal intervention.
For maintenance teams, this model reduces troubleshooting time by offering reliable readings and stable operation under fluctuating load conditions. Students in automation labs benefit from learning PID tuning on actual industrial hardware. Whether you're stabilizing process heat in furnaces or managing batch-based thermal control systems, the TK4W-14RN offers the accuracy and durability required in modern industrial setups.
