Industrial temperature control

The Autonics TZN4M-R4C is a standard-type temperature controller built for electricians and process engineers who need precise regulation in panels and machinery. It accepts a wide range of thermocouple, RTD and analogue inputs to suit many sensor types.

Input and cycle constraints

Sampling runs at a fixed 500 ms cycle, which sets the practical response limit for fast-changing thermal loads. The unit operates on 100-240 VAC at 50/60 Hz, so it fits global mains supplies without external adaptation.

Panel-mount build and wiring

A red 4-digit 7-segment LED display gives clear set-point and process-value reading in bright or dim environments. Current output of DC 4-20 mA connects directly to standard actuator or recorder loops, simplifying cabinet wiring.

Questions about this item

Which control method should I choose for my application?

The controller supports ON/OFF, P, PI, PD, PIDF and PIDS modes. Select PIDF or PIDS for processes needing derivative action, or ON/OFF for simple switching tasks.

What does the 500 ms sampling cycle mean for my process?

The unit updates its measurement and control output every 500 ms, so temperature changes faster than this may not be corrected until the next sample.

How does the 4–20 mA current output limit what I can connect?

The control output is a 4–20 mA current signal, so it drives devices that accept this standard loop signal; voltage-input actuators will need a converter.
