The Autonics TK4M-24CN operates on a 100–240VAC~ 50/60Hz power supply and features a fast 50ms sampling cycle for real-time responsiveness in thermal control loops. It supports multiple control methods including ON/OFF, P, PI, PD, and PID, giving engineers flexibility for both simple and complex processes. A 4-digit 7-segment LED display allows clear visual monitoring during setup and operation. Input compatibility covers a broad range of sensors such as thermocouples (K, J, E, T, R, etc.), RTDs (Pt100Ω, JPt100Ω, Cu100Ω), and analog signals (0–10V, 4–20mA), ensuring reliable integration across systems.
Control output options include SSR drive (11VDC) and DC current (0/4–20mA), allowing direct interfacing with heaters, actuators, or analog input modules. Tuning options such as adjustable proportional band, integral and derivative times, and manual reset provide engineers with precise control over system behavior. The unit is enclosed with an IP65-rated front panel for dust and moisture protection and includes 2kV reinforced insulation for electrical safety. It maintains display accuracy within ±0.3% F.S. and is designed to function reliably between -10°C and 50°C, with up to 85% humidity tolerance. Optional features like CT input, digital input (DI-1), and dual alarm outputs help expand its use in high-performance systems where alerts and diagnostics are critical.
The Autonics TK4M-24CN offers long-term stability, system compatibility, and control accuracy for industries that require consistent thermal regulation. Its input flexibility, output precision, and build quality make it a preferred choice for manufacturers looking to automate and standardize their heat control systems.
