Built for control accuracy and application flexibility, the Autonics TK4M-14SR operates on a 100β240VAC~ 50/60Hz power supply and features a fast 50ms sampling cycle for responsive process adjustments. It supports ON/OFF, P, PI, PD, and PID control methods and provides clear monitoring through a 4-digit 7-segment LED display. The controller handles a broad range of sensor inputs, including thermocouples (K, J, T, E), RTDs (Pt100, JPt100, Cu100), and analog signals such as 4β20mA and 0β10V. Its SSR drive output (11VDC) and relay output (250VAC~ 3A) allow flexible integration with heaters and other control elements.
The unit includes manual reset, hysteresis adjustment, and alarm outputs for added control capability. Accuracy is maintained within Β±0.3% F.S. under standard conditions, and safety is ensured through IP65-rated front protection and 2kV reinforced insulation. The controller weighs approximately 210g and performs reliably across an ambient temperature range of -10Β°C to 50Β°C, with humidity tolerance up to 85% RH. Support for optional CT input and digital input (DI-1) further enhances its adaptability in demanding automation environments.
The Autonics TK4M-14SR is well-suited for retrofitting older systems and deploying in new automation panels. Its proven design, wide input compatibility, and strong environmental protection make it a dependable component for stable thermal control in industrial processes.
