The Autonics TK4H-24RN runs on a universal 100–240VAC~ 50/60Hz power supply and delivers fast feedback through a 50ms sampling cycle, making it ideal for tight thermal control loops. It supports a full range of control modes including PID, PI, PD, P, and ON/OFF, allowing engineers to choose the most appropriate algorithm for their application. Equipped with a 4-digit 7-segment LED display, the controller ensures clear process visibility even in low-light control cabinets.
Sensor compatibility is extensive, supporting thermocouples (K, J, T, R, S), RTDs (Pt100Ω, Cu100Ω), and analog inputs (4–20mA, 0–10V), making integration with legacy and modern sensing systems seamless. The device includes a relay control output (250VAC~ 3A) and optional alarm outputs, with support for CT and digital input signals. The front panel is IP65-rated to withstand dust and water exposure, while the internal circuit offers double insulation and 2kV dielectric strength for operator and device safety. Engineers can fine-tune control characteristics using a proportional band range of 0.1 to 999.9°C, and integral/derivative time settings up to 9999 seconds. The unit's compact design (approx. 211g) makes it suitable for dense panel layouts without compromising on durability or performance.
Pharmaceutical companies use this model in sterilizers and drying ovens where uniform heat distribution is critical for regulatory compliance. Electronics manufacturers rely on it for soldering equipment and curing processes, where any variation in temperature can affect product integrity. Its dual alarm output and CT input support energy monitoring and fault alerts—features especially useful in HVAC and chemical plants. The controller’s easy parameter setting, stable performance, and compatibility with multiple sensors make it a valuable tool for both senior engineers and maintenance teams handling real-time process issues.
Whether you're planning a new control panel, upgrading an aging PLC system, or automating a process line, the TK4H-24RN provides stable, scalable, and intelligent thermal management.
