Temperature controller for industrial processes
The Autonics TZ4M-A4R is a standard-type temperature controller built for electricians and automation technicians who need precise regulation in panels or machinery. It accepts thermocouple, RTD and analogue signals, then drives a relay output to maintain setpoints across heating or cooling loops.
Check your sensor type and supply voltage
Verify that your process uses K, J, E, T, R, S, N or W thermocouples, DPt100O or JPt100O RTDs, or 1-5 VDC, 0-10 VDC and 4-20 mA analogue inputs. The unit operates on 100-240 VAC at 50/60 Hz, so confirm the panel feed matches this range before wiring.
Relay output rated for 250 VAC 3 A
A 4-digit 7-segment LED shows the process value in red, and the relay contact switches loads up to 250 VAC at 3 A. The 500 ms sampling cycle gives responsive ON/OFF, P, PI, PD, PIDF or PIDS control. The compact DIN-rail housing fits standard enclosures, and the box contains one controller.

Questions about this item
Does the box contain only the TZ4M-A4R controller or are sensors and wiring included?
The package supplies one TZ4M-A4R unit; thermocouples, RTDs or analog transmitters must be purchased separately.
Which input type should I select for a K-type thermocouple versus a DPt100 RTD?
Both are supported — choose K (CA) for the thermocouple or DPt100O for the RTD in the input menu.
What does the 250 VAC 3 A relay rating mean for a heater load?
The relay can switch resistive heater circuits up to 250 VAC and 3 A directly; larger loads need an external contactor.
