Autonics TC3YT-B4R3 Temperature Controller Multi Sensor

Autonics TC3YT-B4R3 Temperature Controller Multi Sensor is a DIN 72 × 36 mm panel-mount device that delivers ON/OFF or proportional temperature control for simple process regulation. It accepts J and K thermocouples and Pt100 RTD sensors, drives a single SPDT relay rated 250 VAC at 3 A, and presents a three-digit red LED display with a deviation indicator for easy monitoring. Powered by 100–240 VAC (50/60 Hz), it draws about 4 VA and fits a standard 72 × 36 mm cutout in control panels. This TC3YT-B4R3 belongs to Autonics TC3YT series, commonly used for basic heating/cooling control in equipment like ovens, dryers, and packaging lines where straightforward setup and reliable relay control are needed.
