Autonics TK4M-T4SR is a high-performance temperature controller built to handle a wide range of input signals, including thermocouples, RTDs, and analog signals. It supports control methods like ON/OFF, P, PI, PD, and PID for various process control scenarios. With a sampling cycle of 50ms and a clear 4-digit 7-segment LED display, it ensures fast, accurate feedback in temperature-critical processes. The controller accepts a 100β240VAC~ 50/60Hz power supply and includes both SSR drive and relay output options for flexible system integration. It offers adjustable proportional band, integral, and derivative times to fine-tune your process with accuracy. The unit is enclosed with an IP65-rated front panel, enabling protection against dust and moisture, making it suitable for rugged industrial conditions. Built-in RS485 communication and optional digital inputs enable easy integration into modern PLC and SCADA systems, while double insulation and 2kV dielectric strength enhance safety and reliability.
Designed to withstand ambient temperatures from -10Β°C to 50Β°C and storage up to 60Β°C, the TK4M-T4SR maintains operational integrity in varying environments. Its tolerance for humidity ranges from 35% to 85% RH (non-condensing) ensures stable operation in humid regions. With an approximate weight of 210g, the controller is both compact and robust. Accuracy is assured across input types, maintaining Β±0.3% to Β±0.5% F.S. for thermocouple, RTD, and analog inputs, with hysteresis finely adjustable between 1 and 100Β°C. The insulation is classified as double or reinforced, adding another layer of protection in high-voltage environments. Built-in alarms help monitor deviations in real-time, reducing risk and system downtime. Engineers value the controllerβs intuitive configuration and reliable long-term performance under continuous industrial use.
The Autonics TK4M-T4SR Temperature Controller is widely used in applications such as plastic injection molding, industrial ovens, packaging machinery, food processing units, HVAC panels, and kiln systems. Junior maintenance engineers benefit from its easy-to-learn interface and visual clarity, while senior engineers value its configurability and control precision. Itβs also a preferred model for engineering colleges and training centers teaching real-world PID systems. In plant environments where thermal stability determines product quality or machine safety, the TK4M-T4SR becomes an essential component. View official product details of Autonics TK4M-T4SR.
