Autonics TZN4S-14C PID Temperature Controller

Autonics TZN4S-14C is a dual-PID temperature controller designed for precise process temperature management in automation systems. This digital unit operates from 100 to 240 VAC and provides a current output (4‑20 mA) to drive external actuators or feed a PLC/SCADA input, enabling tight integration into analogue control loops. It features dual PID control channels with auto-tuning capability and two 4‑digit, 7‑segment displays to show process value (PV) and set value (SV) simultaneously. The TZN4S‑14C supports multiple input sensors including thermocouples K/J/R/S/B/E/N and RTD Pt100, allowing deployment across a wide range of applications. The unit belongs to Autonics TZ/TZN family and is commonly used for heating and cooling control in equipment like industrial ovens, furnaces, plastic extruders, packaging machines, and environmental test chambers. Its current-output topology provides smooth control of process loads while maintaining noise immunity, and the device’s PID parameters (P, I, D) can be adjusted to optimize response, with auto-tuning to simplify setup. The compact panel-mount design is built for industrial environments and delivers reliable, repeatable temperature regulation with clear status indicators and straightforward wiring for sensors, power, and current-output loop.
