Temperature controller with relay output

The Autonics TZN4W-R4R is a temperature controller designed for industrial process control. It accepts thermocouple, RTD and analogue inputs and provides a relay output for switching heating or cooling loads. The unit operates on a wide 100-240VAC supply at 50/60Hz.

Check supply voltage and sensor type

Verify that the installation provides 100-240VAC at 50 or 60Hz before wiring the controller. Confirm the process sensor matches one of the supported thermocouple types K, J, E, T, R, S, N, W or the listed RTD and analogue ranges. Ensure the load does not exceed the relay rating of 250VAC 3A.

Red LED display and PID options included

The front panel uses a 4-digit 7-segment red LED for clear temperature readout. Built-in control algorithms cover ON/OFF, P, PI, PD, PIDF and PIDS modes so the same unit can handle simple or complex loops. A 500ms sampling cycle provides responsive regulation without extra modules.

Questions about this item

What comes in the box and do I need to buy thermocouples or RTDs separately?

The box contains one TZN4W-R4R temperature controller. Thermocouples, RTDs or analog transmitters are not included and must be purchased separately to match your process.

The controller accepts K, J, E, T, R, S, N, W thermocouples plus DPt100 and JPt100 RTDs — how do I choose?

Select the sensor type that matches your existing probe or the temperature range and environment of your application; the controller is configured in software for the chosen input.

The relay output is rated 250 VAC 3 A — what load can I actually switch?

You can switch resistive loads up to 3 A at 250 VAC; for inductive loads such as contactors or solenoids use an external snubber or interposing relay to protect the contacts.
