Autonics Corp TZN4H-A4S temperature controller 100-240VAC 50/60Hz

Standard PID temperature controller

The Autonics TZN4H-A4S is a standard-type temperature controller built for industrial process control. It accepts a wide range of thermocouple, RTD and analog input signals for versatile sensor compatibility. The unit operates on a universal 100-240VAC supply at 50 or 60Hz. A 4-digit 7-segment LED display provides clear process value readout.

Multi-mode PID control with SSR drive output

The controller supports ON/OFF, P, PI, PD, PIDF and PIDS algorithms to match diverse thermal loop requirements. Control output is delivered via a 12VDC SSR drive signal suitable for driving external solid-state relays. A fixed 500ms sampling cycle determines the control loop update rate. This output type suits applications using external power switching devices.

Single unit with standard warranty coverage

The product ships as one controller in a box with no additional accessories, cables or software included. Warranty terms cover parts for three years and labor for one year from the supplier. Buyers needing integrated relay contacts, communication interfaces or multi-loop capability must select a different model. The red finish identifies the unit visually on a panel.
