The Autonics TK4S-14SR stands out as a robust and flexible High Performance PID Temp Controller built for demanding industrial processes. With a fast 50ms sampling cycle, it delivers responsive thermal correction through advanced PID, PI, PD, and ON/OFF control modes. Supporting multiple input types—including thermocouples (K, J, R, T, S), RTD sensors like Pt100 and Cu50, and analog signals like 4–20mA or 0–10V—this controller ensures compatibility with legacy and modern process equipment.
Its dual control outputs—SSR drive (11VDC) and relay output (250VAC 3A)—allow it to handle both resistive and inductive loads. Engineers can fine-tune the system using adjustable parameters like proportional band (0.1–999.9%), integral and derivative times, manual reset, and hysteresis control. A 4-digit 7-segment LED display offers real-time visibility of process variables, while display accuracy stays within ±0.3% F.S. for analog, RTD, and thermocouple inputs at room temperature.
Engineered for rugged use, the controller is built with double insulation, a dielectric strength of 2kV, and an IP65-rated front panel that protects against dust and water ingress. It operates reliably from -10°C to 50°C and supports up to 85% relative humidity, making it suitable for India’s diverse industrial climates. Optional digital (DI-1) and CT inputs expand its functionality, offering engineers alarm flexibility and process loop feedback. Its compact form factor (approx. 150g) makes it ideal for space-constrained control panels.
For OEMs, the TK4S-14SR provides the assurance of long-term reliability with strong electrical insulation, optional input functions for alarms or CT sensors, and high display accuracy. Engineering students and technical staff find the controller’s clear PID structure and front-panel programming educational and intuitive.
