The Autonics TK4L-T4CR operates on a power supply range of 100–240VAC~ 50/60Hz, making it compatible with most industrial power setups. With a fast 50ms sampling cycle, it offers real-time responsiveness for accurate process temperature regulation. The controller supports thermocouple, RTD, and analog input signals, ensuring flexibility across varied sensor types. For output control, it features both relay and current (DC0/4–20mA) or SSR drive options. Its control methods include ON/OFF, P, PI, PD, and PID — giving engineers fine-tuned command over thermal systems. Its 4-digit 7-segment LED display provides clear feedback, while adjustable settings like proportional band, integral time, and derivative time allow complete loop tuning. The front panel is rated IP65 for dust and water resistance, and it supports optional RS485 communication and digital input (DI-1/2) for seamless integration into PLC or SCADA environments.
This model ensures long-term durability with double insulation and 2kV dielectric strength between the measuring input and power circuits. It performs reliably in harsh environments, with operational ranges of -10 to 50°C and humidity levels of 35 to 85% RH. The device maintains high display accuracy — ±0.3% F.S. for RTD, thermocouple, and analog signals at room temperature — supporting sensitive process requirements. At a weight of approximately 294g, the TK4L-T4CR is compact and easy to mount within standard control panels. Engineers value its high control accuracy, multi-signal compatibility, fast response time, and robust insulation — all backed by Autonics’ trusted reputation in industrial automation.
The Autonics TK4L-T4CR Temperature Controller is widely applied in plastic processing machines, ovens, HVAC systems, food packaging equipment, drying chambers, and sterilizers — where precise, closed-loop control is vital. It’s especially useful for Indian engineers working in OEM manufacturing, process plants, and retrofitting projects that require advanced PID temperature control with minimal complexity. Engineering colleges and training institutes also prefer this controller for live demonstrations, thanks to its clear interface and rich configuration options.
