AKT7211100 is a KT7 series compact temperature controller designed for precise temperature control in industrial applications. It features a slim DIN rail-mounted form factor with dimensions of 22.5 × 75 × 100 mm, supporting multi-input sensor types including thermocouple, RTD, DC voltage, and DC current inputs. The controller provides relay contact output rated at 1a, 3A, 250V AC for direct load control, with an input accuracy of ±0.2% through advanced PID control algorithms. This configuration includes heater burnout alarm functionality with 10A capacity and is equipped with open collector event output for alarm signaling. The compact design and versatile input/output options make it ideal for process heating systems, industrial ovens, and temperature-critical manufacturing environments where space is limited and reliable temperature regulation is essential.
