Temperature Controller for Industrial Use

The Autonics TZN4W-24S is a standard-type temperature controller designed for process regulation in industrial environments. It accepts a wide range of thermocouple, RTD, and analog input signals for versatile sensor compatibility. The unit operates on a 100-240VAC supply at 50 or 60Hz, making it suitable for global mains voltages. A 4-digit 7-segment LED display provides clear local readout of process values.

Suited for Panel Builders, Not for Compact Spaces

This controller suits engineers and panel builders configuring heating, cooling, or alarm systems that require PID, ON/OFF, or advanced PIDS control modes. The SSR drive output at 12VDC switches solid-state relays directly for reliable actuator control. Installers needing a compact DIN-rail module or a unit with built-in high-current relay contacts should look at alternative form factors. Buyers requiring faster sampling than the 500ms cycle will need a different instrument class.

100-240VAC Universal Mains Input

The single specification that decides fit is the 100-240VAC 50/60Hz power supply range. It allows the controller to connect directly to standard industrial mains without a separate transformer or DC power supply. Verify that the installation site provides AC mains within this voltage and frequency window before ordering. The controller draws operating power from this same connection.

Questions about this item

How do I wire the 100-240VAC supply and the SSR drive output, and which step is most often missed?

Connect live and neutral to the 100-240VAC 50/60Hz terminals, then wire the load to the 12VDC SSR drive output; the step most often missed is setting the input type to match the connected thermocouple or RTD before powering up.

What maintenance or replacement will the TZN4W-24S need over time?

The 4-digit 7-segment LED display may dim after years of continuous operation, and the internal relay contacts can wear from repeated switching cycles.

What limit appears first during sustained PID control at the 500ms sampling cycle?

The 500ms sampling cycle limits how fast the controller can react to rapid temperature changes, so tight loops may overshoot before the next sample corrects the output.
