The Autonics TK4S-R2RN is a compact, high-performance PID temperature controller engineered for rapid and accurate thermal regulation. It supports a wide range of control methods, including ON/OFF, P, PI, PD, and PID, offering flexibility across diverse process environments. Its sampling cycle of 50ms enables fast feedback response, critical in high-precision systems. The controller operates on a stable 24VAC~ 50/60Hz or 24–48VDC supply and is compatible with multiple input types such as thermocouples (K, J, E, T, R, etc.), RTDs (Pt100, Cu50), and analog signals (0–10V, 4–20mA), simplifying integration across different setups. Its dual-layer reinforced insulation ensures safe operation, with 2kV dielectric strength between input and power sections, while the IP65-rated front panel protects against dust and moisture in tough shop floor conditions.
The bright 4-digit 7-segment LED display provides real-time temperature visibility with excellent ±0.3% full-scale display accuracy under standard conditions. Fine-tuning is made easy with adjustable proportional band (0.1–999.9%), integral and derivative time settings (0–9999 sec), and hysteresis ranging from 0.1 to 100.0°C/℉. For process feedback and alarms, it includes a reliable relay output rated at 250VAC~ 3A, and supports optional alarm or transmission outputs (DC 4–20mA). The controller’s compact body weighs approximately 150g, making it ideal for panel installations with space constraints. Operating within an ambient temperature of -10 to 50°C and humidity up to 85% RH, the TK4S-R2RN is built to endure industrial environments with consistent performance over time.
Designed for both general-purpose and advanced automation systems, the TK4S-R2RN is ideal for applications like injection molding, industrial ovens, sterilizers, and reflow soldering machines. For junior engineers, it’s a practical learning tool with a simple interface that builds confidence in setting up PID loops. For experienced technicians, its high configurability, fast response time, and wide input support make it a dependable asset for maintaining process quality and reducing downtime. This model empowers maintenance teams to optimize temperature control without complexity. Learn more on the official Autonics TK4S product page.
