Universal temperature controller, 0-100…°C, hysteresis 0.5-5K, internal setting

ETR 77.009-5

Universal temperature controller, 0-100…°C, hysteresis 0.5-5K, internal setting

Electronic universal temperature controller. Various sensor versions allow universal use in heating, ventilation, air-conditioning, and refrigeration technology as well as in machinery and apparatus engineering. The heating status is indicated by a red LED. Sensors are not included in the scope of delivery. The sensor cable can be extended up to 100 m using a cable cross-section of min. 1.5 mm².
