AUTONICS TZN4W-A4C – Digital Temperature Controller

Autonics TZN4W-A4C is a precision dual-speed PID temperature controller designed for fast stabilization and tight process control in compact 96 x 48 mm panels. TZN4W-A4C supports a wide range of sensors with universal TC/RTD/analog input, allowing a single model to standardize control across equipment. The controller provides a 4-20 mA main control output for seamless interfacing with power controllers or inverters, while TZN4W-A4C adds PV retransmission (4-20 mA) for monitoring and two alarm outputs for process events. High display accuracy (+/- 0.3% FS) with a 500 ms sampling cycle helps TZN4W-A4C maintain stable temperature profiles in ovens, heaters, and packaging lines.
