TZN4S Autonics Temperature Controller
Autonics TZN4S Dual PID Temperature Controller – 48×48 mm, Universal Input
Autonics TZN4S is a 48×48 mm digital PID temperature controller with dual-speed PID control and high accuracy ±0.3% FS.
Supports thermocouple, RTD, and analog inputs, suitable for precise industrial temperature control.
The Autonics TZN4S is a panel-mounted digital PID temperature controller designed for high-precision temperature control in industrial processes. It features dual-speed PID control, enabling fast response during warm-up and stable control with minimal overshoot during steady operation. With universal input support, high display accuracy, and optional alarm, communication, and 4–20 mA retransmission, it is ideal for OEMs, panel builders, and process industries.
