4-digit LED PID Temperature Controller

The Autonics TZN4H-14R is a standard-type temperature controller built for industrial process control. It accepts a wide range of thermocouple, RTD and analog inputs and delivers control through a relay output. The unit operates on a universal 100-240VAC supply.

Suits panel-mount process automation.

This controller fits engineers who need reliable ON/OFF or PID regulation for heating and cooling loops with a 500ms sampling cycle. It is not suited for applications requiring faster sampling, multi-loop coordination or digital fieldbus communications.

Relay output rated 250VAC 3A

The single control output uses a relay contact rated for 250VAC at 3A, limiting direct load switching to small heaters, contactor coils or pilot devices. Larger loads require an external contactor or solid-state relay driven by this output.

Questions about this item

What is the sampling cycle of the TZN4H-14R temperature controller?

The controller samples the input every 500 ms, so the display and control loop update twice per second.

How much heat does the relay output generate during continuous operation?

The relay is rated for 250 VAC at 3 A; its own dissipation is small, but the load current determines the heat produced in the external circuit.

Which power supply must already be present for the TZN4H-14R to operate?

The unit requires a 100-240 VAC 50/60 Hz mains supply, compatible with standard industrial and commercial wiring.
