Autonics TK4N-T4CR is a high-performance temperature controller engineered for precision and reliability in dynamic industrial environments. It operates on a universal 100–240VAC 50/60Hz power supply and delivers a rapid 50ms sampling cycle for accurate thermal feedback. The device supports a wide range of input types—including thermocouples (K, J, T, R, S, B, E), RTDs (Pt100Ω, JPt100Ω), and analog signals (0–10V, 4–20mA)—making it adaptable to diverse equipment setups. The control methods include ON/OFF, P, PI, PD, and PID, with a control period of 0.1 to 120.0 sec depending on output type. Built-in dual control outputs allow for either relay (250VAC, 3A) or current/SSR drive operation, enhancing system integration flexibility.
Equipped with a 4-digit 7-segment LED display, the TK4N-T4CR ensures clear real-time monitoring even in low-light environments. The controller achieves display accuracy of ±0.3% or ±1°C depending on the input type and temperature range, ensuring confidence in every reading. It features strong environmental resistance, operating effectively in ambient conditions from -10°C to 50°C with humidity up to 85% RH. The front panel meets IP65 protection standards and uses reinforced insulation with a dielectric strength of 2kV for safe, long-term operation. An optional RS485 communication interface enables easy integration into PLC or SCADA systems for remote monitoring and control. With a compact body weighing approx. 140g, the unit is ideal for both new projects and retrofit installations.
The Autonics TK4N-T4CR Temperature Controller is used widely in furnace systems, molding machines, food heating applications, HVAC systems, and research test rigs. For junior maintenance technicians, its intuitive interface and reliable feedback reduce the learning curve and minimize setup errors. For senior engineers, the advanced PID tuning, high sensor compatibility, and dual-output options provide complete control flexibility. If you're building or upgrading an automation panel requiring accurate and programmable heat control, this unit offers consistent performance without overcomplicating your system.
