The Autonics TK4S Temperature Controller delivers ultra-high-speed sampling, multi-input flexibility, and dual-loop PID regulation engineered for plastic extrusion lines, packaging sealers, industrial ovens, and pharmaceutical drying chambers.

High-Precision Thermal Regulation with the Autonics TK4S Temperature Controller

Engineered for mission-critical thermal processing, the Autonics TK4S Temperature Controller features an advanced 50 ms measurement sampling cycle that tracks rapid temperature fluctuations with minimal overshoot. The controller integrates independent heating and cooling control outputs, allowing operators to execute simultaneous dual-stage thermal management in applications such as blown-film extrusion, mold temperature skids, and environmental test chambers.

The unit supports universal multi-input selection, enabling technicians to switch between multiple thermocouple types, resistance temperature detectors (Pt100/JPt100), and standard analog voltage or 4–20 mA current loops directly from the parameter configuration menu. Its clear dual-line LED display presents process value (PV) and setpoint value (SV) simultaneously with high contrast, while built-in Modbus RTU communication enables parameter synchronization across plant automation networks.

Frequently Asked Questions

What is the advantage of the 50 ms sampling cycle on the TK4S?
Standard temperature controllers operate on 250 ms to 500 ms cycles. The 50 ms sampling rate on the Autonics TK4S Temperature Controller allows the PID algorithm to react five to ten times faster, preventing temperature dips and overshoots during dynamic production cycles.

Can the control output be changed from SSR drive to 4–20 mA current?
On models equipped with selectable analog outputs, the output mode can be toggled via software between standard SSR pulse drive and continuous 4–20 mA DC current control.

Does the controller support digital communication with PLCs?
Yes. TK4S models with the -B suffix feature an RS-485 serial port supporting Modbus RTU communication, allowing controllers to be networked directly to PLC communication cards or SCADA interfaces.
