Autonics TZN4S-14R digital temperature controller delivers precise, stable control in a compact DIN 48 x 48 mm form factor. TZN4S-14R uses dual-speed PID with auto-tuning to shorten settling time while reducing overshoot. With universal input support (TC, RTD, analog) and a relay main output, the controller integrates easily across diverse process panels. The model includes one event (alarm) output for monitoring. TZN4S-14R operates on 100–240 VAC for flexible deployment.
