Standard temperature controller

The Autonics TK4L-T4RR is a panel-mounted temperature controller designed for industrial process regulation. It accepts a wide range of thermocouple, RTD and analog input signals. The unit provides ON/OFF, P, PI, PD and PID control modes with a 50 ms sampling cycle. A 4-digit 7-segment LED display shows the process value and set parameters clearly.

Users needing PID control with relay output

This controller suits engineers who require versatile input compatibility and standard PID algorithms for heating or cooling loops. The front panel meets IP65 protection for wash-down environments. Buyers who need a solid-state output for faster cycling or higher current loads should look at a different model. Applications requiring more than one control output or dual alarm relays are not supported by this hardware.

Relay output rated 250 VAC 3 A

The primary control output is a mechanical relay rated for 250 VAC at 3 amperes resistive load. This contact switches the heater or cooler directly in many panel installations. The relay rating determines the maximum switched power without an external contactor. Verify that the connected load stays within this voltage and current limit before wiring.

Questions about this item

How can I confirm the TK4L-T4RR is controlling temperature correctly after wiring?

Watch the 4-digit 7-segment LED display for stable process value and setpoint readings; the 50 ms sampling cycle updates the screen quickly.

What comes in the box with the TK4L-T4RR and what must I source separately?

The box contains one standard-type temperature controller; thermocouples, RTDs, analog sensors and RS485 cabling are sold separately.

Which control output version should I choose for a 250 VAC 3 A load?

The TK4L-T4RR provides a relay output rated at 250 VAC 3 A, matching that load requirement.
