The Autonics TK4S-T2RN High Performance PID Temp Controller is built to deliver fast, stable, and highly accurate temperature control across various industrial setups. It supports a wide input power range of 24VAC~ 50/60Hz or 24–48VDC and features a 50ms sampling cycle for quick response. With support for ON/OFF, P, PI, PD, and full PID control methods, engineers can fine-tune systems to handle precise process requirements.
This model accepts a broad range of inputs, including thermocouples (K, J, S, T, etc.), RTDs (Pt100, Cu50), and analog inputs like 0–10V and 4–20mA. The output is provided via a relay rated at 250VAC~ 3A. A 4-digit 7-segment LED display ensures visibility even in low-light conditions, while RS485 communication enables easy integration into SCADA and PLC systems. IP65-rated front panel protection and reinforced 2kV insulation provide additional safety and reliability in dusty or high-interference environments. Display accuracy is maintained within ±0.3% full-scale under standard room temperature. Engineers often select the TK4S-T2RN for its compact footprint, strong electrical safety features, and durable construction suited for long-term industrial performance.
Engineers value this model for its consistent operation, clean signal communication, and integration-friendly design. Junior technicians benefit from the simple user interface and real-time display, while senior engineers appreciate the precision of PID tuning and system feedback. Additional models can be found under the Autonics Temperature Controllers category. For complete product lines from the brand, refer to the Autonics Sensors & Controllers section. The model TK4S-T2RN is particularly suited for long-cycle, high-accuracy thermal applications in industrial environments.
