Industrial Temperature Controller

The Autonics TZ4M-R4R is a standard-type temperature controller designed for process automation. It accepts thermocouple, RTD and analog voltage or current inputs. The unit operates on a wide 100-240VAC supply and provides a relay control output rated at 250VAC 3A. It suits engineers needing versatile sensor compatibility in a single DIN-rail module.

Continuous Process Regulation

Sampling occurs every 500ms to maintain tight loop response during extended production runs. The controller supports ON/OFF, P, PI, PD, PIDF and PIDS algorithms for stable regulation under varying thermal loads. The 4-digit 7-segment LED display presents the process value clearly for operator monitoring. Relay switching handles heater or cooler circuits directly without an external contactor.

Panel-Mount Reliability

The red housing is built for industrial panel mounting and daily operational visibility. Screw terminals secure sensor and power wiring against vibration in machinery environments. A three-year parts and one-year labor coverage period reflects the manufacturer's confidence in component durability. The compact form factor allows dense integration inside electrical cabinets.

Questions about this item

How much power does the TZ4M-R4R draw when running continuously on a 240V supply?

The controller operates on 100-240VAC 50/60Hz; the relay output is rated 250VAC 3A, so continuous draw depends on the connected load.

What sensor types can I connect directly to the TZ4M-R4R without extra modules?

It accepts thermocouples K, J, E, T, R, S, N, W, RTDs DPt100O and JPt100O, plus 1-5V, 0-10V and 4-20mA analogue signals.

Will the TZ4M-R4R replace my older panel meter that uses a 4-20mA loop?

Yes, the analogue input supports DC 4-20mA directly, so it can serve as a drop-in replacement for that loop.
