PID temperature controller

The Autonics TZN4L-14C is a standard-type PID temperature controller designed for industrial process regulation. It accepts a wide range of thermocouple, RTD and analogue input signals for versatile sensor compatibility. The unit provides a current output of DC4-20mA for driving actuators or recording equipment. A 4-digit 7-segment LED displays the process value and set parameters clearly.

Suitable applications and limits

This controller suits engineers and electricians who need configurable ON/OFF, P, PI, PD, PIDF or PIDS control modes in a single panel-mount device. It operates on a universal 100-240VAC supply at 50 or 60Hz without external adapters. Buyers who require a faster sampling cycle than 500ms should consider alternative models. Those needing relay or voltage control outputs instead of a current loop will need a different unit.

Deciding specification

The control output type is fixed as a DC4-20mA current signal, which determines compatibility with your final control element. Verify that your valve positioner, drive or recorder accepts this specific current loop standard. The input specification covers the most common thermocouple and RTD types plus standard voltage and current ranges. Power supply acceptance of 100-240VAC simplifies installation across global mains voltages.

Questions about this item

How do I decide between the thermocouple, RTD and analog input options on this controller?

Choose the input type that matches your sensor: thermocouples K, J, E, T, R, S, N or W; RTDs DPt100Ω or JPt100Ω; or analog signals 1–5 VDC, 0–10 VDC or 4–20 mA.

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

The controller updates its measurement and adjusts the output every 500 ms, providing responsive PID or ON/OFF control for most industrial heating and cooling loops.

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

The single current output drives actuators or recorders that accept 4–20 mA signals; it cannot directly switch high-power loads without an external interface.
